One cannot create a PV on a partitioned device, and therefor such
devices where not reported to Engine. This proved surprising to users
who woder where their LUN disappeared.
Vdsm should report all devices, and ovirt-engine should mark partitioned
devices as unworthy of a PV. In the future, Vdsm may allow to forcefully
remove a partition table from a device, to make it usable as a PV.
Douglas (CCed) would take resposibilty on the Vdsm side. Initial patch at
http://gerrit.ovirt.org/944 sports a backword-compatible API. Who's taking this
on Engine? This involves GUI, too, as partitioned devices should probably be
