Would you be kind to try starting a VM from virsh, where the VM image

I am asking you to have a VM image somewhere on your local disk, chown
it to vdsm:kvm mode 0660, create a libvirt domxml for it (something
simple, no spice or encryption), and try to start it up.
Would this fail to start with the same permission issue, and the issue
is again solved by `chown vdsm:qemu` ? If so, please copy libvir-list
with your reply.
Dan.
It seems it doesn't solve for me...
