Hello Daniel,

Thanks for inputs.

Also, one more problem we observed in 4.0.5. When creating VM, we cannot 
change the CPU, sockets, cores. It will not allow us to change anything. 
We have to save the VM during creation with 1 vCPU. Again, edit VM and 
change the vCPU parameters. Have you or anyone observed this behaviour?

Thanks & Regards,

I don’t know of a function built into oVirt for scheduling snapshots. 
If you don’t already you may want to setup an export domain (NFS 
based), on separate storage.
Just a reminder: snapshots are not backups and they should only be 
kept temporarily. We use this tool for backups:
https://github.com/wefixit-AT/oVirtBackup
It’s not the most efficient as it clones a VM from a snapshot, then 
exports the clone – so you’re transferring the same data twice. But it 
works for our purposes. We have this running in a cron job.
If anyone has come up with a script that uses the newer API to export 
a snapshot directly, please share!
We get the same error when adding a disk while creating the VM (In 
Chrome, Firefox, and Safari on OS X Sierra client). This is reportedly 
fixed in 4.0.6 per this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1394175
Could someone with 4.0.6 confirm that?
Best,
Daniel

Hello to oVirt Users,
I have few questions.
a. Can we schedule the VM snapshots? If yes, please share the procedure
b. Snapshots are stored on the same storage domain. Can we move them 
to another storage domain say NFS domain for additional safety? If, 
yes, please share the procedure.
Also, after upgrading to version 4.0.5, at many places, especially 
when we are creating a new VM and trying to create a new Disk for the 
VM, we keep getting "uncought exception" and the process will not 
complete. We have to create a VM, without Disk and then create the 
disk separately and attach it to VM.
Is anyone else facing this issue? These sort of issues were not there 
in 4.0.4.
