Re: [libvirt] [PATCH v2 09/12] conf: Add SCSI hostdev check for disk drive address already in use

https://bugzilla.redhat.com/show_bug.cgi?id=1210587 (partial) If a SCSI subsystem <hostdev> element address is provided, we need to make sure the address provided doesn't conflict with an existing or libvirt generated address for a SCSI <disk> element. This will fix the issue where the domain XML provided an <address> for the <hostdev>, but not the <disk> element where the address provided ends up being the same address used for the <disk>. A <disk> address is generated using it's assigned <target> 'dev' name prior to the check/validation of the <hostdev> address value.
