Yep -- there was a small interface change that broke
save/restore/migrate, and I promised to fix it, but I just
haven't had a chance with OLS and admin etc.

I'll work on it over the weekend, if not before.

At one point, we talked about xm having a "-U" option where a URL
was used to specify the xend to talk to. I don't think it's there
in the current version, but it should be trivial to add. You'd
then be able to control and query multiple xen nodes from a
single host. Anyone want to have a go to add this?
