description: Can you please try older vzctl version? Say, latest 2.7.0-x, and please report if it works or not. This is probably a bug in vzctl due to latest changes, we will try to find it out as soon as next Monday.

description: I apologize. I have found a source of a problem. It has begun, when I have made the following: #echo 'FreeBSD 4.10-RELEASE-p2' > /proc/sys/kernel/virt_osrelease In this connection a question. Whether it is possible to use it, and if yes, how? From changelog of 2.6.8-022stab070.1: diff-ve-virt-osrelease-20060220 Patch from Alexander, modified by Denis: This patch virtualizes kernel version in `uname -a` and VPS /proc/version. it is inherited on VPS start from /proc/sys/kernel/virt_osrelease

description: It is possible to use this, but ELF loader checks kernel version to make sure that executables are compatible with kernel ABI. So you cannot write _any_ arbitrary text to this variable It should be something like "2.x...". For example, it should work fine with "2.6.8", "2.6.x-any-text", "2.4.X-..." and so on. You can write "2.6.x FreeBSD 4.10-RELEASE-p"

description: Just another question. Is it ok, what in vps'es we have both, and virt_osrelease and osrelease sysctl variables? # sysctl -a | grep osrelease error: "Invalid argument" reading key "net.ipv4.route.flush" error: "Operation not permitted" reading key "kernel.cap-bound" kernel.virt_osrelease = 2.6.18 kernel.osrelease = 2.6.8-022stab078-up `uname -r` get his value from kernel.virt_osrelease, but I can just look right version of kernel from sysctl...

description: this feature was added not to fake people and make them believe they have different kernel, but rather some applications/glibc.
