In the libvirt XML you would set the partition name to: /machine/dahlia this corresponds to a systemd slice call machine-dahlia.slice If you wanted a third level you'd need to create machine-dahlia.slice and also create machine-dahlia-foo.slice, making sure the latter had After=machine-dahlia.slice. Then the libvirt name would be listed as /machine/dahlia/foo 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
