[ovirt-users] Sparse VMs from Templates - Storage issues

Hi all, 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. My questions. 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. Shantur
