I just downloaded the latest version from jit with:

git clone git://git.openvz.org/pub/linux-2.6.24-openvz
linux-2.6.24-openvz.org

(hope that is correct)

configuration, compilation worked without problem (compiling for amd64).

but when i try to start a VE I get the following error:

any idea whats wrong?

I've seen the same yesterday:

Feb  8 14:02:22 zut kernel: Symbol sys_open is marked as UNUSED, however this module is using it.
Feb  8 14:02:22 zut kernel: This symbol will go away in the future.
Feb  8 14:02:22 zut kernel: Please evalute if this is the right api to use, and if it really is, submit a report the linux kernel mailinglist together with submitting your code for inclusion.

I've reverted to .22 since, but will be happy to try again...

I had the same problem but I see there is a bug report for that:

http://bugzilla.openvz.org/show_bug.cgi?id=802

I did have the fair scheduler on and after disabling this:

# zgrep CONFIG_FAIR /proc/config.gz
# CONFIG_FAIR_GROUP_SCHED is not set


it works.
