Hi Kir,
[root@mrmber ~]# uname -a
Linux mrmber.mainphrame.net 2.6.32-042stab052.8 #1 SMP Wed Mar 14 16:02:48
MSK 2012 i686 i686 i386 GNU/Linux
There was no dmesg content generated by the attempt to create the CT with
ploop layout; /var/log/vzctl.log contained only this:
2012-03-22T17:01:46-0700 vzctl : CT 779 : Unable to get full ostemplate
name for debian-5.0-x86
2012-03-22T17:01:46-0700 vzctl : CT 779 : Creating image:

2012-03-22T17:01:46-0700 : PLOOP_IOC_ADD_DELTA

2012-03-22T17:01:46-0700 vzctl : CT 779 : Creation of container private
area failed
