New subject: [libvirt] [PATCH 1/2] libxl: support creating guest with USB hostdev
Support creating guest with USB host device in config file.
Currently libxl only supports xen PV guest, and only supports
specifying USB host device by 'bus number' and 'device number'.

Yes, this and the following has problem to fit for both within 80 columns
and correct indention. Change indention to let it fit within 80 columns?

New subject: [libvirt] [PATCH 2/2] libxl: support hotplug USB host device
Support hot attach/detach a USB host device to guest.
Curretnly libxl only supports xen PV guest, and only
supports specifying USB host device by 'bus number'
and 'device number'.

Probably a nice follow-up after this series is in, would be to add the
USB
subsys type to domain capabilities (that you address in the OVMF series)

Yes, good point. I'll add it to that series if this one makes it in first.
Speaking of the OVMF series, I've fixed a few things after more testing and will
rebase and resend a V2. Thanks in advance if either of you have time to look at it.

I will certainly have a look at it. I actually started but didn't wanted to
comment
without testing a bit first too - I will wait for the V2. I specially like the nice
cleanup you make on the capabilities side plus getting domain capabilities
implementated :)
