This looks like a great addition but I wonder if it is of any real use
without supporting multipath? On SANs issuing I/O to some paths might
cause severe performance penalties or the LUN might be visible but I/O
is rejected until an explicit switch over command is sent. This would be
handled transparently if multipath would be used on top.
Any plans to add this? (Otherwise I might give this a try once I'll find
some more free time to spend on libvirt again).
Cheers,
