I'm not in any position to say who should do what between vdsm and libvirt. However, the end result for device assignment to work with an unprivileged guest is that someone needs to change file ownership on those pci sysfs files before qemu is launched or before devices are hot added to a guest. libvirt does this for a purely libvirt managed guest. In the example we saw yesterday, nobody was doing it. Thanks, Alex -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
