Hi Peter, I think problems listing below is related with this bug. So I list my steps here. Please help to confirm it. Description of problem: fail reverting guest to snapshot to running/paused status when guest using glusterfs volume Version-Release number of selected component (if applicable): qemu-kvm-rhev-1.5.3-19.el7.x86_64 libvirt-1.1.1-12.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1. create an guest with glusterfs volume # virsh dumpxml rhel6 .. <disk type='network' device='disk'> <driver name='qemu' type='qcow2'/> <source protocol='gluster' name='gluster-vol1/rhel6-qcow2.img'> <host name='10.66.106.22' port='24007' transport='rdma'/> </source> <target dev='vda' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </disk> <controller type='scsi' index='0' model='virtio-scsi'> <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/> </controller> .. 2. create an running status snapshot for guest # virsh snapshot-list rhel6 Name Creation Time State ------------------------------------------------------------ 1384506518 2013-11-15 17:08:38 +0800 running this snapshot is created in comment 0 3. revert guest to snapshot to running status # virsh snapshot-revert rhel6 1384506518 --running ;virsh list --all Id Name State ---------------------------------------------------- - rhel6 shut off Actual results: as above Expected results: guest should be running in step 3 Additional info: Problems in comment 0 and comment 1 are both related with lines "<controller type='scsi' index='0' model='virtio-scsi'> .. </controller>" because if i delete these three line then do the test, it works well; or if i keep these three line and change line "<target dev='vda' bus='virtio'/>" to "<target dev='sda' bus='scsi'/>", it work well also. However, if i use file type disk, it work well on all situations above. There is a similar bug 1031943. i think.
Yes I think that bug 1031943 causes this issue too. Closing as duplicate. *** This bug has been marked as a duplicate of bug 1031943 ***
