[libvirt] [PATCH 0/4] qemu_hotplug: Check for duplicate drive addresses

[Michal Privoznik]

This is an alternative approach to:

https://www.redhat.com/archives/libvir-list/2019-March/msg01111.html

which caused regression to which a proposed fix is here:

https://www.redhat.com/archives/libvir-list/2019-April/msg00756.html

One of the selling points was that having this check in
virDomainDefCompatibleDevice() will fix the problem across all drivers.
Well, turns out, some drivers don't care (e.g. lxc) and some have a
different workflow and thus don't need that check.

Michal Prívozník (4):
  conf: Expose virDomainSCSIDriveAddressIsUsed
  qemuhotplugtest: Don't plug a SCSI disk at unit 7
  qemu_hotplug: Check for duplicate drive addresses
  Revert "domain_conf: check device address before attach"
