[ovirt-users] How to obtain vm snapshots status

Hi! I use ovirt rest api to start vm, backup vm and then remove vm. I start vm, wait for vmstatus up, then start backup, wait for starting, finalize, wait for succeeded, wait for disk unlock. Looks like backup is finished here from my side.Because ovirt repost succeed status and unlocks disk. But if i try shutdown and remove vm ovirt will throw error Cannot remove VM. The VM is performing an operation on a Snapshot. Please wait for the operation to finish, and try again. Ok, ovirt is right here, I see from web interface that operation hasn't finished yet. How can I obtain correct status where vm can be removed? I also tried to get info about vm snapshots but all of them had Status: ok
