hello,

when C7.4 was = released in early August 2017. The above bug report was

The CentosPlus = kernel was patched soon after and that gave us a workaround. Most = frustrating to me was the flaw in 7.4 bootable media and also the = pxeboot images. This meant we couldn't boot into a xen pv install using = the `official` media ISO's.

I went ahead to = build a new pxeboot pair based on the CentosPlus repaired kernel and = then I remastered the minimal ISO using those tools. Below I show my = fixed pxeboot pair.

Good news for us/you is this pv kernel limitation is a = singular problem limited to the default C7.4 kernel and you have many = options to workaround. Not only the CentosPlus kernel works to boot your = domU, but also the elrepo kernel-LT and kernel-ML.

Hello,

Where did I go wrong?

I used `git-format-patch` and exported= the 193 odd patches to stable-4.10.
I took my recent delta (*.deb= ian.tar.xz) for stretch (deb9.4), cleared (reset) debian/patches, then adju= sted the series.

When tried to build the source:
dpkg= -buildpackage -nc -S -d

I received error after error from the = 76th patch onwards. This is inside the comet merge patchset. Anyone else tr= ied to use these patches with the 4.10.0 tarball?

I know the 4= .10.1 minor release is coming soon, so why worry about it.

cheers,
PryMar56

We are experiencing domU crashes while live-migrating and in the seconds after the live-migration has been completed. This doesn't happen all the time. But we are able to reproduce the issue within 1 to max 10 times live migrating between 2 dom0s. We've reproduced this so far with domUs running Linux 4.9.82-1+deb9u3 (Debian Stretch) and 4.15.11-1 (Debian Buster). Attached are all kernel traces, oopses per crash that are logged from the domUs and retrieved via "xen console" in the seconds after the live-migration is completed. In some cases the domU keeps on running or being visible via "xen list", in other cases the domU disappears from "xen list" after a short amount of time. >From the logging in our dom0s in most cases everything looks fine: Apr 12 16:58:20 altair socat[738]: migration target: Ready to receive domain.

Hello,

 

We are starting the project with X86 CPU, and we hav= e consideration to use Hypervisor for following reasons:

·         Isolating CPU Cores for hard real time dedic= ated tasks (CPU Core fast response to IRQ and deterministic behaviour)=

·         Running Bare-metal applications on isolated = CPU Cores

 

We need Linux OS on one CPU Core to be housekeeping = OS, initializing other isolated CPU Cores to start applications. We are als= o having in mind to use PCIe for DMA to/from FPGA board.

 

Is this applicable to Xen ?

 

Thank you for your time.

 

With best regards,

 

Nikola

charset=utf-8 Content-Language: en-GB Content-Transfer-Encoding: quoted-printable Hi, I have been setting up a new server to run Xen, but can't seem to get the machine to boot the hypervisor correctly. The server has UEFI firmware and I don't think we can run it in BIOS compatibility mode because the particular hardware configuration requires full UEFI support in order for everything to work. I have installed Debian Stretch on the server and can boot via UEFI into GRUB and then Linux just fine. I have tried following the directions found on this page in order to get Xen booting: https://wiki.xenproject.org/wiki/Xen_EFI I have found that the Debian xen-hypervisor-4.8-amd64 package installs a file at /boot/xen-4.8-amd64.efi. Should I be able to use this as my EFI boot file? Or do I still need to actually compile Xen from sources in order to get a working 'xen.efi' file? I have tried copying all files from the /boot directory into /boot/efi/EFI/xen/ and then creating /boot/efi/EFI/xen/xen-4.8-amd64.cfg with the following contents: [global] default=3Dxen [xen] options=3Dconsole=3Dvga loglvl=3Dall noreboot kernel=3Dvmlinuz-4.9.0-6-amd64 root=3DUUID=3Dc0589119-f679-4b3c-ac62-7a686ffe00b9 ro ramdisk=3Dinitrd.img-4.9.0-6-amd64 I then created an EFI boot entry pointing at Xen: efibootmgr -w -L Xen -l "\EFI\xen\xen-4.8-amd64.efi" -c When I try to boot from that menu entry, the machine's firmware just returns to system setup or to the boot menu, suggesting to me that it doesn't recognise or isn't able to boot from xen-4.8-amd64.efi. I also tried renaming that file to xen.efi and having the config in xen.cfg just in case that made a difference, but the result was the same. I have tried booting Debian without using GRUB, using the kernel EFI stub to boot, according to the instructions at 'https://wiki.debian.org/EFIStub'. I got that to work for booting the normal kernel, so I know I can boot the mainline Linux kernel directly from the EFI firmware without GRUB, but I've not been able to boot the Xen hypervisor. Any suggestions or advice would very much appreciated.

Hi,

When I upgrade to Xen 4.= 11, I got the following when creating any guest:

Robert, Thanks for your suggestions. I tried with your suggested 'efibootmgr' command and it set up a boot entry identical to the one I already had. I only have one ESP partition on this machine right now, so if I leave out those parameters, it looks like the system correctly guesses the location of the ESP partition for me anyway. However, I installed an EFI shell and was able to try booting the xen-4.8-amd64.efi file from the EFI shell. The output I got was this: **** Xen 4.8.3 (c/s ) EFI loader Using configuration file 'xen-4.8-amd64.cfg' vmlinuz-4.9.0-6-amd64: [snip long hex numbers] initrd.img-4.9.0-6-amd64: [snip long hex numbers] Read failed for initrd.img-4.9.0-6-amd64: ErrCode 0x8000000000000004 **** Some searching online turned up these links: https://www.mail-archive.com/xen-devel@lists.xenproject.org/msg08323.html= https://datacentersupport.lenovo.com/es/es/solutions/ht506400 That error code apparently means EFI_BAD_BUFFER_SIZE, meaning the EFI implementation can't read arbitrarily sized blocks, so the firmware doesn't correctly read larger files when loading the Xen EFI stub. In this case I suspect it's because the initrd.img file is about 18MB in size with the firmware able to cope with files up to 16MB. That second link above seems to suggest a patch to the Xen code that will produce a xen.efi file which works around the initrd.img block size issue. I am tempted to try patching and compiling Xen in order to get a xen.efi file that will hopefully work around the file size issue. Has anyone else run up against this problem? Any suggestions as to the best way to get the hypervisor and dom0 booting in this situation? Thanks in advance for any help, it's turned out to be a very long process getting this new server up and running...

(= XEN)_event_channel.c:319:d0v3_EVTCHNOP_failure:_domain_1,_error_-= 22

This behavior is not seen when using Xen 4.10-s= table.
Any idea?

charset=utf-8 Content-Language: en-US Content-Transfer-Encoding: quoted-printable Hi John, It turns out that on Friday I was able to get Xen booting directly from UEFI, without using GRUB at all. I followed the instructions on this page about getting the hypervisor to boot directly from UEFI: https://wiki.xenproject.org/wiki/Xen_EFI#Xen_as_EFI_binary_.28loading.29 However, it looks like our server's UEFI firmware has problems reading files bigger than 16MB if there is no additional chunking or buffering done. That issue is described on this page, along with a patch to the hypervisor sources that works around the problem: https://datacentersupport.lenovo.com/gb/en/solutions/ht506400 I ended up having to apply that patch and then compile the kernel in order to get a xen.efi file that would work on our server, but now it is working and the server is booting just fine. I may file a bug report about this, though I'm not familiar with the UEFI specification to know whether this is considered a UEFI firmware bug or something that should be fixed in the hypervisor/kernel code.

Trying to boot via the EFI shell, I found the UEFI firmware complained that it couldn't open the initrd.img file. It looks like the EFI firware has trouble reading the initrd.img file because it's over 16MB in size, as described on these pages: https://www.mail-archive.com/xen-devel@lists.xenproject.org/msg08323.html= https://datacentersupport.lenovo.com/gb/en/solutions/ht506400 In the end, I applied the patch found at the bottom of that Lenovo page and custom compiled my own hypervisor kernel. That solved the problem and I could get Xen to boot. I may file a bug report about this, though I am unsure whether it should be considered a bug in the server's UEFI firmware or whether it should be considered a bug in the kernel. Maybe I should think of it as a 'feature request' for the kernel. Thanks again for your help, in any case.

Hi

 

WIKI says hu= gepage is supported in hypervisor and domU, my question is whether hugepage= is also supported on DOM0 OS? If yes, how to enable it?

ISSUE DESCRIPTION ================= The workaround for the Meltdown vulnerability (XSA-254) failed to deal with an error code path connecting the INT 80 handling with general exception handling. This results in an unconditional write attempt of the value zero to an address near 2^64, in cases where a PV guest has no handler installed for INT 80 on one of its vCPU-s. IMPACT ====== A malicious or buggy guest may cause a hypervisor crash, resulting in a Denial of Service (DoS) affecting the entire host. VULNERABLE SYSTEMS ================== All Xen versions which the XSA-254 fixes were applied to are vulnerable. Only x86 systems are vulnerable. ARM systems are not vulnerable. Only x86 PV guests can exploit the vulnerability. x86 PVH and HVM guests cannot exploit the vulnerability. MITIGATION ========== Running only PVH or HVM guests avoids the vulnerability. CREDITS ======= This issue was discovered by Andrew Cooper of Citrix. RESOLUTION ========== Applying the appropriate attached patch resolves this issue. xsa259.patch xen-unstable, Xen 4.10.x ... xen 4.7.x xsa259-4.6.patch Xen 4.6.x $ sha256sum xsa259* 5c14a90af066c952974324b361e2a428c280f876b854f0c85a78e8579054a4d1 xsa259.meta ff2efb5eb2502ded988d0aa15351030a15494a9e2223eafbb88377a8e4d39dcb xsa259.patch c40bc8802077cf73f8393fb50574b7c7efbc4d127e202b0ebd757d34aa07aac3 xsa259-4.6.patch $ DEPLOYMENT DURING EMBARGO ========================= Deployment of the patches and/or mitigations described above (or others which are substantially similar) is permitted during the embargo, even on public-facing systems with untrusted guest users and administrators. But: Distribution of updated software is prohibited (except to other members of the predisclosure list). Predisclosure list members who wish to deploy significantly different patches and/or mitigations, please contact the Xen Project Security Team. (Note: this during-embargo deployment notice is retained in post-embargo publicly released Xen Project advisories, even though it is then no longer applicable. This is to enable the community to have oversight of the Xen Project Security Team's decisionmaking.)

ISSUE DESCRIPTION ================= QEMU handles many different file formats for virtual disks (e.g., raw, qcow2, vhd, &c). Some of these formats are "snapshots" that specify "patches" to an alternate disk image, whose filename is included in the snapshot file. When qemu is given a disk but the type is not specified, it attempts to guess the file format by reading it. If a disk image is intended to be 'raw', but the image is entirely controlled by an attacker, the attacker could write a header to the image, describing one of these "snapshot" formats, and pointing to an arbitrary file as the "backing" file. When attaching disks via command-line parameters at boot time (including both "normal" disks and CDROMs), libxl specifies the format; however, when inserting a CDROM live via QMP, the format was not specified. IMPACT ====== An attacker supplying a crafted CDROM image can read any file (or device node) on the dom0 filesystem with the permissions of the qemu devicemodel process. (The virtual CDROM device is read-only, so no data can be written.) VULNERABLE SYSTEMS ================== Only x86 HVM guests with a virtual CDROM device are affected. ARM guests, x86 PV guests, x86 PVH guests, and x86 HVM guests without a virtual CDROM device are not affected. Only systems with qemu running in dom0 are affected; systems running stub domains are not affected. Only systems using qemu-xen (aka "qemu-upstream" are affected; systems running qemu-xen-traditional are not affected. Only systems in which an attacker can provide a raw CDROM image, and cause that image to be virtually inserted while the guest is running, are affected. Systems which only have host administrator-supplied CDROM images, or systems which allow images to be added only at boot time, are not affected. MITIGATION ========== One workaround is to "wrap" the guest-supplied image in a specific format; i.e., accept a raw image from the untrusted user, and convert it into qcow2 format; for example: qemu-img convert -f raw -O qcow2 untrusted.raw wrapped.qcow2 WARNING: Make sure to specify `-f raw` if you do this, or qemu will "guess" the format of "untrusted.raw" (which the attacker may have crafted to look like a qcow2 snapshot image with an alternativee base). Another workaround is to allow guests to only change CDROMs at boot time, not while the guest is running. CREDITS ======= This issue was discovered by Anthony Perard of Citrix. RESOLUTION ========== Applying the appropriate attached patch resolves this issue. xsa258.patch xen-unstable, Xen 4.10.x, Xen 4.9.x xsa258-4.8.patch Xen 4.8.x, Xen 4.7.x xsa258-4.6.patch Xen 4.6.x $ sha256sum xsa258* 2c35a77eeca5579b5c32517c5ba511c836fa70f8b824ca8883fc6e1a7e608405 xsa258.meta 7e8014deae4fa19464fe6570d0719f8f0d7730dd153d58b2fa38b0cd5ed2e459 xsa258.patch 2c58060a42dafbf65563941dd8c737732124b49eb47007cc60f647553227f557 xsa258-4.6.patch ebba2f1f084249cd1e1c2f59e338412161884c31c83dbba03fc1e10bf4ba57a1 xsa258-4.8.patch $ DEPLOYMENT DURING EMBARGO ========================= Deployment of the patches and/or the "wrap" mitigation described above (or others which are substantially similar) is permitted during the embargo, even on public-facing systems with untrusted guest users and administrators. However, deploying the "only allow guests to change CDROMs at boot time" is NOT permitted (except where all the affected systems and VMs are administered and used only by organisations which are members of the Xen Project Security Issues Predisclosure List). Specifically, deployment on public cloud systems is NOT permitted. This is because it may give attackers a hint of where to look for the vulnerability. Deployment of this mitigation is permitted only AFTER the embargo ends. Additionally, distribution of updated software is prohibited (except to other members of the predisclosure list). Predisclosure list members who wish to deploy significantly different patches and/or mitigations, please contact the Xen Project Security Team. (Note: this during-embargo deployment notice is retained in post-embargo publicly released Xen Project advisories, even though it is then no longer applicable. This is to enable the community to have oversight of the Xen Project Security Team's decisionmaking.)

--00000000000029e6f3056aebb99b Content-Type: text/plain; charset="UTF-8" Hi All. We have brought up the cubieboard2 from almost scratch, following are the steps done : == u-boot == u-boot has been compiled using bleeding-edge mainline (ec5c4a8fd64a178a4d159917cda0aa176e5a9be5), via : * make Cubieboard2_defconfig * make ARCH=arm CROSS_COMPILE=/home/ajay/arm-toolchain-6.2/arm-linux-gnueabihf- This gives us u-boot-sunxi-with-spl.bin == kernel == kernel also has been compiled using bleeding-edge mainline (6d08b06e67cd117f6992c46611dfb4ce267cd71e) via : * make clean * make ARCH=arm sunxi_defconfig menuconfig In the menu, enabled following additional features : * General setup => System V IPC * General setup => POSIX Message Queues * Kernel features => Xen guest support on ARM * make -j$(nproc) ARCH=arm CROSS_COMPILE=/home/ajay/arm-toolchain-6.2/arm-linux-gnueabihf- zImage * make -j$(nproc) ARCH=arm CROSS_COMPILE=/home/ajay/arm-toolchain-6.2/arm-linux-gnueabihf- sun7i-a20-cubieboard2.dtb This gives us zImage and sun7i-a20-cubieboard2.dtb. == integration, and starting up == Followed the steps as per https://github.com/maronai/cubieboard/wiki/3.1.-Compiling-mainline-kernel-for-CubieBoard2-and-CubieTruck, but with following differences : a) Used u-boot-sunxi-with-spl.bin, zImage, sun7i-a20-cubieboard2.dtb from above steps. b) Used (and compiled to boot.scr) the following boot.cmd : fatload mmc 0 0x46000000 zImage fatload mmc 0 0x49000000 sun7i-a20-cubieboard2.dtb setenv bootargs console=ttyS0,115200 rw root=/dev/mmcblk0p2 bootz 0x46000000 - 0x49000000 c) Extracted debian-wheezy-7.5-armhf.com-20140603.tar to the rootfs partition on the sd-card. d) Finally, inserted the sdcard in cubieboard2, following are the brief bootup logs : ################################################################## U-Boot SPL 2018.05-rc2-00118-gec5c4a8 (Apr 28 2018 - 08:40:48 +0530) DRAM: 1024 MiB CPU: 912000000Hz, AXI/AHB/APB: 3/2/2 Trying to boot from MMC1 U-Boot 2018.05-rc2-00118-gec5c4a8 (Apr 28 2018 - 08:40:48 +0530) Allwinner Techy CPU: Allwinner A20 (SUN7I) Model: Cubietech Cubieboard2 I2C: ready DRAM: 1 GiB MMC: SUNXI SD/MMC: 0 Loading Environment from FAT... *** Warning - bad CRC, using default environment Failed (-5) In: serial Out: serial Err: serial SCSI: SATA link 0 timeout.

I have gone through https://xenbits.xen.org/docs/unstable/misc/arm/device-tree/booting.txt, but am not sure what exact changes are needed. As mentioned somewhere at the last in the link, we would prefer if no changes in uboot are required, and the dom0-bootup can be achieved by only changing the dt(s/b) file at https://github.com/torvalds/linux/blob/master/arch/arm/boot/dts/sun7i-a20-cubieboard2.dts Will be grateful for help.

Hi All.

We have brought up the cubieboard2 from almost scratch, following are the steps done :

 <snip>

=3D=3D getting xen ready =3D=3D

i)
Compiled xen on cubieboard itself, via :

=C2=A0=C2=A0 * sudo dpkg -i dist/xen-upstream-4.11-unstab= le.deb
=C2=A0=C2=A0 * sudo reboot

ii)
Upon reboot, "sudo xl list" gives following :

This means that /dev/xen/privcmd (or the legacy /proc/xen/privcmd) device isn't available.

First check that you have actually booted Xen with Linux as dom0.=C2=A0 You don't show any logs in this final section, and simply installin= g the debball and rebooting won't typically cause Xen to be the head of the boot list.

Yes, I have= n't been able to setup xen bootup.

That's why, re= quested help regarding the changes that are required in https://github.com/torvalds/linux/blob/master/arch/arm/boot/dts/sun= 7i-a20-cubieboard2.dts, that would cause dom0 to boot up.

Yes, I haven't been able to setup xen bootup.

We have brought up the cubieboard2 from almost scratch, following are the steps done :

i)
Compiled xen on cubieboard itself, via :

=C2=A0=C2=A0 * git clone git://xenbits.xen.org/xen.git
=C2=A0=C2=A0 * cd xen
.=C2=A0 * ./configure --libdir=3D/usr/lib

Upon reboot, "sudo xl list" gives foll= owing :

This means that /dev/xen/privcmd (or the legacy /proc/xen/privcmd) device isn't available.

First check that you have actually booted Xen with Linux as dom0.=C2=A0 You don't show any logs in this final se= ction, and simply installing the debball and rebooting won't typically cause Xen to be the head of the boot list.

Yes, I haven't been able to setup xen bootup.

That's why, requested help regarding the changes that are required in = https://github.com/torvalds/linux/blob/master/arch/arm/boot/dts/s= un7i-a20-cubieboard2.dts, that would cause dom0 to boot up.


Sorry for the confusion.

Ah - sorry.=C2=A0 I misunderstood.=C2=A0 I'm afraid you're goin= g to have to wait for some people more knowledge about ARM to answer.

I made some changes :

a)
Removed the cha= nged from the dts file.
Instead changed boot.cmd to

However, I see absolutely no change in the observations; no xen-related = log on the serial-console, and "sudo xl list" gives the same erro= r messages.

What am I lacking?

This means that /dev/xen/privcmd (or the legacy /proc/xen/privcmd) device isn't available.

First check that you have actually booted Xen with Linux as dom0.=C2=A0 You don't show any logs in this final se= ction, and simply installing the debball and rebooting won't typically cause Xen to be the head of the boot list.

Yes, I haven't been able to setup xen bootup.

That's why, requested help regarding the changes that are required in = https://github.com/torvalds/linux/blob/master/arch/arm/boot/dts/s= un7i-a20-cubieboard2.dts, that would cause dom0 to boot up.


Sorry for the confusion.

Ah - sorry.=C2=A0 I misunderstood.=C2=A0 I'm afraid you're goin= g to have to wait for some people more knowledge about ARM to answer.

ISSUE DESCRIPTION ================= QEMU handles many different file formats for virtual disks (e.g., raw, qcow2, vhd, &c). Some of these formats are "snapshots" that specify "patches" to an alternate disk image, whose filename is included in the snapshot file. When qemu is given a disk but the type is not specified, it attempts to guess the file format by reading it. If a disk image is intended to be 'raw', but the image is entirely controlled by an attacker, the attacker could write a header to the image, describing one of these "snapshot" formats, and pointing to an arbitrary file as the "backing" file. When attaching disks via command-line parameters at boot time (including both "normal" disks and CDROMs), libxl specifies the format; however, when inserting a CDROM live via QMP, the format was not specified. IMPACT ====== An attacker supplying a crafted CDROM image can read any file (or device node) on the dom0 filesystem with the permissions of the qemu devicemodel process. (The virtual CDROM device is read-only, so no data can be written.) VULNERABLE SYSTEMS ================== Only x86 HVM guests with a virtual CDROM device are affected. ARM guests, x86 PV guests, x86 PVH guests, and x86 HVM guests without a virtual CDROM device are not affected. Only systems with qemu running in dom0 are affected; systems running stub domains are not affected. Only systems using qemu-xen (aka "qemu-upstream" are affected; systems running qemu-xen-traditional are not affected. Only systems in which an attacker can provide a raw CDROM image, and cause that image to be virtually inserted while the guest is running, are affected. Systems which only have host administrator-supplied CDROM images, or systems which allow images to be added only at boot time, are not affected. MITIGATION ========== One workaround is to "wrap" the guest-supplied image in a specific format; i.e., accept a raw image from the untrusted user, and convert it into qcow2 format; for example: qemu-img convert -f raw -O qcow2 untrusted.raw wrapped.qcow2 WARNING: Make sure to specify `-f raw` if you do this, or qemu will "guess" the format of "untrusted.raw" (which the attacker may have crafted to look like a qcow2 snapshot image with an alternativee base). Another workaround is to allow guests to only change CDROMs at boot time, not while the guest is running. CREDITS ======= This issue was discovered by Anthony Perard of Citrix. RESOLUTION ========== Applying the appropriate attached patch resolves this issue. xsa258.patch xen-unstable, Xen 4.10.x, Xen 4.9.x xsa258-4.8.patch Xen 4.8.x, Xen 4.7.x xsa258-4.6.patch Xen 4.6.x $ sha256sum xsa258* 2c35a77eeca5579b5c32517c5ba511c836fa70f8b824ca8883fc6e1a7e608405 xsa258.meta 7e8014deae4fa19464fe6570d0719f8f0d7730dd153d58b2fa38b0cd5ed2e459 xsa258.patch 2c58060a42dafbf65563941dd8c737732124b49eb47007cc60f647553227f557 xsa258-4.6.patch ebba2f1f084249cd1e1c2f59e338412161884c31c83dbba03fc1e10bf4ba57a1 xsa258-4.8.patch $ DEPLOYMENT DURING EMBARGO ========================= Deployment of the patches and/or the "wrap" mitigation described above (or others which are substantially similar) is permitted during the embargo, even on public-facing systems with untrusted guest users and administrators. However, deploying the "only allow guests to change CDROMs at boot time" is NOT permitted (except where all the affected systems and VMs are administered and used only by organisations which are members of the Xen Project Security Issues Predisclosure List). Specifically, deployment on public cloud systems is NOT permitted. This is because it may give attackers a hint of where to look for the vulnerability. Deployment of this mitigation is permitted only AFTER the embargo ends. Additionally, distribution of updated software is prohibited (except to other members of the predisclosure list). Predisclosure list members who wish to deploy significantly different patches and/or mitigations, please contact the Xen Project Security Team. (Note: this during-embargo deployment notice is retained in post-embargo publicly released Xen Project advisories, even though it is then no longer applicable.

guest may crash Xen with XPTI UPDATES IN VERSION 3 ==================== CVE assigned. ISSUE DESCRIPTION ================= The workaround for the Meltdown vulnerability (XSA-254) failed to deal with an error code path connecting the INT 80 handling with general exception handling. This results in an unconditional write attempt of the value zero to an address near 2^64, in cases where a PV guest has no handler installed for INT 80 on one of its vCPU-s. IMPACT ====== A malicious or buggy guest may cause a hypervisor crash, resulting in a Denial of Service (DoS) affecting the entire host. VULNERABLE SYSTEMS ================== All Xen versions which the XSA-254 fixes were applied to are vulnerable. Only x86 systems are vulnerable. ARM systems are not vulnerable. Only x86 PV guests can exploit the vulnerability. x86 PVH and HVM guests cannot exploit the vulnerability. MITIGATION ========== Running only PVH or HVM guests avoids the vulnerability. CREDITS ======= This issue was discovered by Andrew Cooper of Citrix. RESOLUTION ========== Applying the appropriate attached patch resolves this issue. xsa259.patch xen-unstable, Xen 4.10.x ... xen 4.7.x xsa259-4.6.patch Xen 4.6.x $ sha256sum xsa259* 5c14a90af066c952974324b361e2a428c280f876b854f0c85a78e8579054a4d1 xsa259.meta ff2efb5eb2502ded988d0aa15351030a15494a9e2223eafbb88377a8e4d39dcb xsa259.patch c40bc8802077cf73f8393fb50574b7c7efbc4d127e202b0ebd757d34aa07aac3 xsa259-4.6.patch $ DEPLOYMENT DURING EMBARGO ========================= Deployment of the patches and/or mitigations described above (or others which are substantially similar) is permitted during the embargo, even on public-facing systems with untrusted guest users and administrators. But: Distribution of updated software is prohibited (except to other members of the predisclosure list). Predisclosure list members who wish to deploy significantly different patches and/or mitigations, please contact the Xen Project Security Team. (Note: this during-embargo deployment notice is retained in post-embargo publicly released Xen Project advisories, even though it is then no longer applicable.

charset="UTF-8" Hi All, I posted this out to the centos-virt mailing list and was asked by dunlapg at umich.edu to post it here instead with some additional info (config file of a VM, dmesg before a hang from inside a VM and dmesg after hang from Dom0), so here's the original email, plus the extras at the bottom: Hi, I've tried hitting up the CentOS forums and thought I'd try here too as I don't seem to be getting any bites. We've been in the process of migrating all our hypervisors over to CentOS 7 using Xen. Once we had a few up and running we started to notice that the DomU's would randomly freeze. They become unresponsive to any network traffic, stop consuming CPU resources on the hypervisor and it's not possible to log in to the console locally using: virsh console We can sometimes get as far as typing a username and hitting return, but the DomU just hangs there. It doesn't seem to matter what Linux distro the DomU is running, it affects them all. The only way we can get them back is by destroying and recreating them (far from ideal!). After a bit of research and digging around, we eventually found these 2 nuggets: https://wiki.gentoo.org/wiki/Xen#Xen_domU_hanging_with_kernel_4.3.2B https://www.novell.com/support/kb/doc.php?id=7018590 They both advise adding the command line argument: gnttab_max_frames=256(the default is 32). We applied this change and all hypervisors rand stable for around a week until DomU's started freezing again (we've since tried even higher values, to no avail). More research later led me to https://bugs.centos.org/ view.php?id=14258 and https://bugs.centos.org/view.php?id=14284 (which are essentially the same report). There hasn't really been any movement on these tickets unfortunately, but I have +1'd them. Have any others had issues with Xen and DomU's locking up in CentOS 7? Are there any other fixes/workarounds? If any additional info is needed that isn't already in the bug tickets or forum post, please let me know and I'll be happy to provide whatever is required (these freezes are happening at least once a day). Any help would be much appreciated and would mean my Ops guys could get a decent sleep! Cheers Darren Additional info as requested: Config file for one of the frozen VMs (there are other VMs with fewer interfaces some with more memory, some with more vCPUs): t02red02 bdbc6df1-e153-0dac-9a92-faa7b1270e97 2097152 2097152 1 /usr/bin/pygrub linux destroy restart restart
