so any thoughts on getting around this issue guys?

2010/3/26 Martinx - ããããã <thiagocmartinsc@xxxxxxxxx>
Sure! My /boot partition is at the beginning of the disc and it is ext2.


2010/3/26 Outback Dingo <outbackdingo@xxxxxxxxx>
more information is its running ext4 from lvm on sda5Â

/dev/sda5 on / type ext4 (rw,errors=remount-ro)
proc on /proc type proc (rw)

so in the grub config i have

cat /etc/grub.d/40_custom
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. ÂSimply type the
# menu entries you want to add after this comment. ÂBe careful not to change
# the 'exec tail' line above.

Mmm... Your system is 64 bits?!
You try the Linux 2.6.32.10 from Jeremy's tree without Xen?!

2010/3/26 Outback Dingo <outbackdingo@xxxxxxxxx>
hrmm ok, well Ive gotten all the way to the end and tried to reboot into XEN


during the boot process i see

elf_xen_note_check

will only load images built for generic load or linux images

Panic on CPU0

could not setup DomU Guest OS

reboot in 15 seonds

any thoughts???



2010/3/26 Martinx - ããããã <thiagocmartinsc@xxxxxxxxx>
Hi!


ÂThis is a quick guide to help us to try the new Xen.
ÂAlso I have the composite window manager on top of the Xen! With full 3D support!

ÂTo achieve this I do:

1- Install your Ubuntu Desktop 10.4 beta1 and upgrade your system;

1.1 - Install some packages:

Âaptitude install build-essential libncurses5-dev dpkg-dev debhelper fakeroot

2- Download and install a new kernel with dom0 pv_ops enabled:

Âsudo -s
Âcd /usr/src
Âgit clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-xen
Âcd linux-2.6-xen
Âgit pull
Âgit reset --hard
Âgit checkout -b xen/stable origin/xen/stable
Âgit pull

2.1 - Download the kernel config file attached to this mail (config-for-xen-2.6.32.10-pvops):

ÂCopy the config file to the kernel source dir:

Âcp ~Downloads/config-for-xen-2.6.32.10-pvops /usr/src/linux-2.6-xen/.config

ÂYou can see the differences of my config file against the Lucid one:

Âdiff /boot/config-2.6.32-17-generic ~Downloads/config-for-xen-2.6.32.10-pvops | vim -

Â...both are close to each other.

2.2 Configure, compile and install:
Â
Âmake menuconfig # Enable the dom0 support and the Xen backend/frontend/xenfs stuffs...
Âmake
Âchmod g-s /usr/src -RÂÂÂ Â# To avoid the error: "dpkg-deb: control directory has bad permissions 2755 (must be >=0755 and <=0775)"
Âmake dep-pkg
Âdpkg -i ../linux-image*2.6.32.10*.deb
Âdepmod 2.6.32.10
Âupdate-initramfs -c -k 2.6.32.10
Âupdate-grub
Âecho "xen-evtchn" >> /etc/modules

ÂNow you can try your new kernel without Xen, if you want, it should work smootly.

3- Download and install the latest Xen:

ÂPreparing your environment:

Âapt-get build-dep xen-3.3
Âaptitude install uuid-dev iasl texinfo

ÂDownload and compile:

Âcd /usr/src
Âhg clone -r 4.0.0-rc8 http://xenbits.xensource.com/xen-unstable.hg
Âcd xen-unstable.hg
Âmake xen
Âmake tools
Âmake stubdom
Âmake install-xen
Âmake install-tools PYTHON_PREFIX_ARG=
Âmake install-stubdom

Âupdate-rc.d xend defaults 20 21
Âupdate-rc.d xendomains defaults 21 20

4- Configuring your Grub2 through the file /etc/grub.d/40_custom:

---- cut here ----
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change
# the 'exec tail' line above.
menuentry "Xen 4.0.0-rc8 / Ubuntu 10.4 kernel 2.6.32.10 pvops" {
insmod ext2
set root=(hd0,1)
multiboot (hd0,1)/xen-4.0.0-rc8.gz dummy=dummy
module (hd0,1)/vmlinuz-2.6.32.10 dummy=dummy root=/dev/mapper/HyperDeskVG01-tcmc--dell--lucid ro
module (hd0,1)/initrd.img-2.6.32.10
}
---- cut here ----

ÂDon't forget to change your "root=" option of your Linux!

ÂRun update-grub again:

Âupdate-grub

5- Reboot into your new dom0!

Âreboot

6- Look if your Xen is up and running

Âxm list
Âxm info

Â.. if not:

/etc/init.d/xendomains stop
/etc/init.d/xend stop
/etc/init.d/xend start
/etc/init.d/xendomains start

Âxm list
Âxm info

-
ÂCheers!
ÂThiago
