I really need some help in getting this to work. This seems pretty simple, just tell nova-compute to ignore any instance named Domain-0 (actually it could ignore any instance not named 'instance-XXXXXXXX'). As there is a libvirt type to connect to xen, it is in openstack interest to fix this. As I did make it work with a flawed old libvirt in Ubuntu 10.04, this seems close to working.
Could anyone help me in this? I will be happy to test it. If I try to find how to do it myself in my spare time it could take a lot more time than I have in my hands for this. Even some kind of advice of where I could put this ignore code would help and I could contribute with the project with the resulting code. Thanks.
