[libvirt] [PATCH 0/5] Additional SCSI generated device address checks

https://bugzilla.redhat.com/show_bug.cgi?id=1210587 These patches will resolve a couple issues with generation of the <address type='drive' .../> for a SCSI <disk> and <hostdev>. The <disk> generation algorithm 'assumes' that when presented with <target dev='sda'.../> that it can use controller=0 and unit=0 since sda would conceivably be the first device; however, a <hostdev> could attempt to assign itself to that address and it doesn't have a target device name, so it bypasses the virDomainDiskDefDstDuplicates checks that would normally 'catch' two <disk>'s attempting to use the same name. Likewise, if a <hostdev> occupies an <address> and we attempt to hotplug a <disk> without providing an address, the address generation could attempt to place the disk on the already existing host device.
