[libvirt-users] Suspend Domain (virsh suspend) or Freeze Filesystems (virsh domfsfreze) to take Snapshot of ISCSI volume

Hi everybody, I am trying to take snapshot of a particular iscsi disk mounted inside the guest operating system. I have created my own snapshot feature for that. Could someone please suggest the better choice for stopping read/write operations on disk out of the two to take snapshots, or if you have any better solution, 1) freeze filesystems ( using domfsfreeze ) and then take the snapshot or, 2) suspend the VM ( using virsh suspend ) and then take the snapshot And, before taking the snapshots what other operations should i perform ( like sync or flush buffer ) for a consistent snapshot. Any help would be greatly appreciated. Best Regards, Payes
