We have always been on CentOS7 - never 6. We have had many corrupt VMs from using the scheduled volume snapshot functionality... We had to turn off the ability to do volume snapshots while a VM is powered-on... We also stopped using VM Snapshots since the Delete VM Snapshot functionality deletes snapshots the same way as volume snapshots are deleted from the qcow2 files (after the snap is backed up to secondary storage). We are hoping the pause VM, delete snapshot, resume VM fixes this - we are still testing
