Hi!
Today I restarted hardware node and find that my CTs didn't start.
When I trying start it I get next error:
# vzctl start 101
Error: required UB parameter swappages not set
Error: detected vswap CT config but kernel does not support vswap
The CT config:

There is part of output of `strace vzctl start 101':
rt_sigaction(SIGINT, {0x1, [], SA_RESTORER, 0x31a18302f0}, NULL,  = 0
ioctl(4, 0x400c2e05, 0x7fffdb494a10) = -1 ESRCH (No such process)
ioctl(4, 0x400c2e05, 0x7fffdb494820) = -1 ESRCH (No such process)
access("/proc/vz/vswap", F_OK) = -1 ENOENT (No such file or directory)
write(2, "Error: detected vswap CT config "..., 65Error: detected vswap CT config but kernel does not support vswap) = 65
write(2, "\n", 1
) = 1

Replied in bugzilla, copy-paste from bz follows:
Now, the problem is your physpages is not set the way it should. Newer vzctl is just able to detect it, while the old one didn't care. So this is the bug with your CT configuration, not vzctl.
If you look up the description of physpages (http://wiki.openvz.org/Physpages#physpages), you will note this:
> For older kernels, physpages is an accounting-only parameter.
> The barrier should be set to 0 and the limit to 'unlimited' (LONG_MAX).
So, the way to fix your CT config is:
vzctl set NNN --physpages 0:unlimited --save
Again, I am really sorry that new vzctl broke your CT start, but the problem is indeed with CT config not vzctl.
