Thank you for answer! The point of removing it is that we do *not* want people to add custom code into nova's internal APIs, so there is explicitly no replacement for this functionality. If you have a use case that Nova does not currently address, that is broadly useful then you can propose a blueprint/spec to explicitly support this in Nova, rather than doing it out of tree via a hook 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 :|
