[ovirt-users] VM Snapshot Problem

Hi All, I am facing one strange problem with the snapshot of the VM...let me explain .... I have one vm called “vm1” & i have created the following snapshots :- 1) 2014-08-20 First Snapshot 2) 2014-08-21 Second Snapshot 3) 2014-08-22 Third Snapshot Now if i try to restore the VM(means commit) with Third Snapshot...other two snapshots will exists.. But if I restore the VM with First Snapshot...VM will restore successfully but it destroy the other 2 snapshosts (Second Snapshot & Third Snapshot)..that means both the other snapshots will be disappear.... Please let me know is this the limitation of Ovirt or it's any setting problem... Thank you.
