This will break libvirt when run against existing sheepdog releases which still have the name 'collie'. Libvirt needs to detect which command name is used and pick the right one to use, not just hardcode one of them.

This is wrong; you need to test for both names, and use the correct one, in order to be back-compat safe. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

I missed the point of compatibility. I'll post v2 which doesn't break it later. Thanks, Hitoshi
