I found the qemu user yesterday and added it to the input group. All is good now. The patches work great! Are they being added to the main code base soon? A small faq on the site detailing libvirt usage and adding qemu to the input group would be needed though.
I notice no bugs as of yet. The mouse fully disengages from each system unlike an earlier report I read in this mailing list. This is perfect and precisely what I requested many months ago when vfio-users mailing list first started. :)
Thanks for all your work on this,
Jon
