CEPH is just a file system, why do you think it should be different?

Not my choice of a distro, especially for KVM, but that's an entirely different conversation.

comment Recover an oVirt Hosted Engine Crash
So, the image is either corrupted or inaccessible, start debugging gluster first (and that's a totally different issue really)

comment Recover an oVirt Hosted Engine Crash
qemu-img info and qemu-img check would do, to start with. If they pass, go over the file permissions. Since this is gluster based, also check that side of things

comment CentOS Qemu+KVM lot of virtual machine processes
Thanks. I expected to find io-threads in the disk xml, but it might still be the default. When you run ps -ef |grep VMNAME, do you see threads there? Also, when you stop the two VMs, do all these processes go away?

comment CentOS Qemu+KVM lot of virtual machine processes

comment Revert libvirt external snapshot
Case 1: there might in fact be a solution through virsh, but it will be simple orchestration of the same solution. Case 2: it's not going back/forth on reverts, it's basically branching out. I'll add the solution in the answer
