[Users] Container creation hangs forever

[Nirmal Guhan]

I don't think there is any kernel crash. I ran gdb and this is where
it waits for ever. Any other command (from other sessions) too hang
after this point :(

(gdb) run enter 50
Starting program: /usr/sbin/vzctl enter 50
Container is not running

Program exited with code 037.
Missing separate debuginfos, use: debuginfo-install vzctl-3.0.23-1.i386
(gdb) run start 50
Starting program: /usr/sbin/vzctl start 50
Warning: distribution not specified default used /etc/vz/dists/default
Starting container ...
