On some VMs (especially one Windows server 2016 64bit with 500 GB of disk).= Guest agents are installed at VMs. i almost always observe that during the= backup of the VM the VM is rendered unresponsive (dashboard shows a questi= on mark at the VM status and VM does not respond to ping or to anything). For scheduled backups I use: https://github.com/wefixit-AT/oVirtBackup The script does the following: 1. snapshot VM (this is done ok without any failure) 2. Clone snapshot (this steps renders the VM unresponsive) 3. Export Clone 4. Delete clone 5. Delete snapshot Do you have any similar experience? Any suggestions to address this? I have never seen such issue with hosted Linux VMs. The cluster has enough storage to accommodate the clone.
