[ovirt-users] vdsmd and libvirtd services failed to start

Hi, I have a HCI setup running on 3 nodes and created 6 VM's. Was running IO (like dd and linux untar) on those VM's overnight. Next day i saw that for 2 of the nodes vdsmd and libvirtd services failed and if manually started, they don't come up. All the VM's state has changed to 'unknown' and failed to migrate. Can someone help looking at the logs and figure out the RCA. Let me know what all logs are needed, i can post the same. Thanks, Bhaskarakiran.
