My test platform is centos-6.2 32 bit. I had successfully created
ploop-based containers when testing the ploop and vzctl from git last
week. Today I installed the released ploop and vzctl rpms to test further.
Which kernel it is?
Anything in dmesg output?
When I issue a command to create a ploop-based container, vzctl is
unable to complete the operation, exiting with errors:
[root@mrmber ~]# vzctl create 777 --layout=ploop --config=vswap-256m
--ostemplate=debian-5.0-x86

When I issue a command to create a container with the same parameters
except using layout=simfs instead of ploop, vzctl succeeds:
[root@mrmber ~]# vzctl create 777 --layout=simfs --config=vswap-256m
--ostemplate=debian-5.0-x86

Where should I be looking to solve this mystery?
