I have a setup as detailed below
- iSCSI Storage Domain
- Template with Thin QCOW2 disk
- Multiple VMs from Template with Thin disk
oVirt Node 4.4.4
When the VMs boots up it downloads some data to it and that leads to increase in volume size.
I see that every few seconds the VM gets paused with
"VM X has been paused due to no Storage space error."
and then after few seconds
"VM X has recovered from paused back to up"
Sometimes after a many pause and recovery the VM dies with
"VM X is down with error. Exit message: Lost connection with qemu process."
and I have to restart the VMs.
1. How to work around this dying VM?
2. Is there a way to use sparse disks without VM being paused again and again?
Thanks in advance.
