The PCI mode is for actual PCI device assignment at the hardware level. This concept doesn't make sense for containers since there's a shared kernel. Instead you want to assign the device nodes from /dev using the mode='capability' hostdev XML instead per this link: http://libvirt.org/formatdomain.html#elementsHostDevCaps Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :| _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
