So, no option to have at the same time snapshotting (qcow2) & VZ running
on a shared storage ? I see GlusterFS doesn't work well with OpenVZ...
Should I just ditch OpenVZ, or use only an external NFS NAS for this?
I'm quite reluctant to have a NFS+ext4 system on the slaves that
replicates, but maybe that is an option...
