Hi,
 I just tried building 2.6.24 with vz from git, and it builds nicely (when
I disable CPT), but trying to boot it - it fails when 'initiating processor
0' ( and machine restarts ). 
 Are such failures interesting and should be reported, or do you prefer
reports from your own testing team and external reports should be only
sent for official releases?

Your reports are needed very much and we very appreciate any feedback from users.

Can you please provide some more info such as .config file you used to build kernel?
Maybe something else specific you have done/configured?

attached and also available at http://kuszelas.eu/~eyck/config-2.6.24

 can't recall anything exotic, with the same config and clean 2.6.24
machine boots OK.
 At first I though that the problem was with 'video=791',
but after changing this it looks like it restarts right after trying to
init processor 0. I ain't got rs232 in this machine, and I don't know what
other way could catch that boot sequence (I think netconsole initializes
way later)

[Box reboots with 2.6.24-openvz from git after
 Initiating processor 0]

Doh! It was indeed descriptors moving in GDT.

The following should fix it:

git diff v2.6.24.. -- arch/x86/boot/compressed/head_64.S arch/x86/kernel/acpi/wakeup_64.S arch/x86/kernel/head_64.S include/asm-x86/segment_64.h  >../1.patch

 Yes, thanks, now it boots, and starts spewing:

This is fine (as in not a problem at all, just message from sysfs
developers to scsi developers).

OK, I haven't seen this.

I must have messed up KERNEL_CS/DS descriptors during forward porting.
Let me recheck.

Chances that you'll get anything on console in such situation are pretty slim.
