Yes, I was planning to talk with you guys in the next day or so to see about making this change.  I wanted to let the changes settle around here first.

That should be handled in the commit immediately following this one: "xenserver: Add monitor-external-ids daemon".  We already needed the ability to monitor ovsdb for other external-id changes, so I just added this to the list of things for which to look out.  I agree that we should make the change in newer versions of XAPI, though.  Does this seem like a reasonable approach?
