<div>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.</div><div>
<br></div><div>When I issue a command to create a ploop-based container, vzctl is unable to complete the operation, exiting with errors:</div><div><br></div><div>[root@mrmber ~]# vzctl create 777 --layout=ploop --config=vswap-256m --ostemplate=debian-5.0-x86</div>

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