Xen project Mailing List

Hi,

I've been struggling with this for a few weeks now.

Trying to install Xen, as per https://wiki.debian.org/Xen

Dell PowerEdge R740xd server with PERC H740P Adapter RAID controller.

Two disk groups (virtual disks) configured. One is 479GB for the OS and one is 4TB for LVM

Boot mode set to UEFI

I installed Debian 9.9 and configured the disks as -

600 GB EFI partition

447.6GB ext4 / (root partition)

32 GB /swap

Machine boots as normal.

Then it comes to Xen.

I went with the default xen-system install, which gives me Xen 4.8.5+shim4.10.2+xsa282-1+deb9u11

If I use EFI to boot, Debian can boot fine, but Xen hangs -

Loading Xen 4.8-amd64 ...

WARNING: no console will be available to OS

Loading Linux 4.9.0-8-amd64 ...

Loading initial ramdisk ...

Nothing else happens. The system hangs there.

If I reboot and try booting to just Debian, it will boot and fun fine.

-----------------------------------------------------------

So, I switched, thinking it's an EFI issue.

Boot mode set to BIOS

Configured the disks during Debian install

Primary partition 447.6 GB ext4 /

Logical partition 32GB swap

I installed Debian 9.9, and put GRUB loot loader in the MBR. (/dev/sda)

Machine boots as normal. I installed firmware-linux-nonfree

Machine boots as normal.

When it reboots I get the following -

[ 22.424146] mce: Unable to init device /dev/mcelog (rc: -16)

[ 22.806814] megaraid_sas 0000:86:00.0: Failed from megasas_alloc_request_fusi on 495

Gave up waiting for suspend/resume device

Gave up waiting for root file system device. Common problems:

- Boot args (cat /proc/cmdline{

- Check rootdelay= (did the system wait long enough?)

- Missing modules (cat /proc/modules; ls /dev)

ALERT! UUID=ffc22a21-fb8c-4e85-8f72-e2435ef8e6c5 does not exist. Dropping to a shell!

BusyBox v1.22.1 (Debian 1:1.22.0-19+b3) built-in shell (ash)

Enter 'help' for a list of built-in commands.

(initramfs)

(initramfs) cat /proc/cmdline

placeholder root=UUID=ffc22a21-fb8c-4e85-8f72-e2435ef8e6c5 ro quiet

(initramfs) cat /proc/modules; ls /dev

It lists a load of devices, but no /dev/sd devices and no UUID devices.

If I reboot and select Debian (no Xen), then the system will boot fine.

Any ideas?
