Applications like OpenStack use migration as their upgrade mechanism. ie to upgrade a new version of Nova, you would install it on a new compute host and migrate your guests across. For nova to fix its buggy usage, users would have to upgrade Nova in-place on existing nodes which is contrary to its normal practice of using migration for all upgradess Regards, Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://entangle-photo.org -o- http://search.cpan.org/~danberr/ :| -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
