I'm still getting the CHOWN (0,0) error.   I have a work around in place at the moment, where by my NFS storage is exported with no_root_squash (not desired, and should not be necessary given that QEMU is running as oneadmin).

Once it starts, selecting it and clicking Shutdown simply returns the machine back to running state on the next poll interval.   I've also disabled apparmor for libvirt by touching /etc/apparmor.d/disable/usr.sbin.libvirtd.
