[libvirt] [PATCH 0/2] qemu: Fix <address/> is ignored for USB disks

This is a follow-up to https://bugzilla.redhat.com/show_bug.cgi?id=861309 If one has USB disks configured for domain with explicit <address/>, libvirtd ignores that node when building qemu command line. So, disk is connected to the first free USB port implicitly by qemu. That breaks other USB devices which have explicit <address/> - ports they should be connected to may be already occupied by disks. With first patch applied, if one has USB disk connected to the USB hub, qemu fails to start, because it does not know anything about hubs yet (when parsing disks). That's why second patch is needed. Vladislav Bogdanov (2): qemu: Do not ignore address for USB disks qemu: pass -usb and usb hubs earlier, so USB disks with static address are handled properly
