Nobody has any ideas or thoughts on how to troubleshoot? why does qemu group work but not kvm when qemu is part of kvm group? [root@ovirt1 prod vdsm]# grep qemu /etc/group cdrom:x:11:qemu kvm:x:36:qemu,sanlock qemu:x:107:vdsm,sanlock On 5/18/16 3:47 PM, Bill James wrote:
another data point. Changing just owner to qemu doesn't help. Changing just group to qemu does. VM starts fine after that.

Some added info. This issue seems to be just like this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1052114
I have verified that chown qemu:qemu of disk image also fixes the startup issue. I'm using raw, not qcow images.
