Subject: [PATCH] vm.Vm._getUnderlyingDriveInfo: extract path of gluster disks

_getUnderlyingDriveInfo() is broken by design. It has no reliable means
to match Engine-requested devices with libvirt-produced ones. As a
heuristic, it uses the device's as matching key. However, before this
patch, it failed to extract the path from the xml definition of gluster
disks.
