Hi Evan, I guess you are referring my post from end of june about VMs terminating all of a sudden. http://lists.gnu.org/archive/html/qemu-discuss/2014-06/msg00094.html Good to hear that others are facing the same error. Your mail arrives only 3 days after we hit the error the second time. To sum up my environment/situation: - NFS based storage for images. - hypervisor is running in an OVirt cluster (shouldn't be relevant) - Affected VM OS: SLES 11 SP3 - Error occured during "heavy" disk I/O while running backups inside VM We have no real clue what is going on. Comparing that with your scenario I would not blame the VM. The issue must be somewhere in the lower layers of the stack. But it's just a guess. If I find time I will open a Redhat bugzilla. Markus.
