You know if this checking for guests were done in the virNetworkDestroy API implementation in src/network/bridge_driver.c, instead of in virsh, then we would not need any of this code for extending the XML nor parsing it in virsh. We could simply check the number of connections which is something we have directly available internally. So 95% of this patch series would go away Regards, 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 :| -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
