It's a known issue: on 028stab033 checkpointing is broken! It's fixed in git already with the following patch: http://git.openvz.org/?p=linux-2.6.18-openvz;a=commit;h=650723f83a8685111fb3dee7073454861c446193
So, in order to use checkpointing you can:
1) use 031 kernel before 034 is released
2) compile fresh kernel from git
Sorry for inconvenience!

I am using ubuntu feisty, making packages with:
After some time, I am getting boot prompt
(initramfs) ....
and message:
cannot find: /dev/mapper/Ubuntu-root
System obviously cannot find my SATA disk and LVM volumes.
I have used the same procedure and same .config to build kernel packages stable033 and stable031, and I had no problems.

Ernad]]>hernad2007-06-06T09:11:16-00:00Re: Failed to dump VE

"init_premount / udev 21
cannot create /proc/sys/kernel/hotplug ... operation not permitted"
Is it initrd? Or init already?
I can say you it if you post here the full log of kernel boot...
Thank you,

Here is the script:
# It's all over netlink now
echo "" > /proc/sys/kernel/hotplug <<<< LINE 21
# Start the udev daemon to process events
/sbin/udevd --daemon
# Iterate sysfs and fire off everything; if we include a rule for it then
# it'll get handled; otherwise it'll get handled later when we do this again
# in the main boot sequence.
/sbin/udevtrigger

I have checked, thre is no difference between initrd.img of this 033-HEAD, stab033 i stab031 kernel.
I don't know how to provide you log of initrd process.
System cannot acces root file system (/dev/mapper/Ubuntu-root).
Thank you.

vzctl reported the sam problem as with stab033.
Maybe I should get the new vzctl ?
