I thought I'd post an update to this old thread.  I've gone ahead and
installed Linux-HA on a couple linux-vservers.  That really is an
improvement over our Xen installation as I can host quite a few sites
on one physical machine.  I have all the same "backupability" that I
had with Xen in case a real machine dies.

Then, on the real servers, I can run the sites that need more
resources on the host os without any virtual server overhead.

I wrote all this up in case anyone is interested in seeing what I've
put together:

Thanks all for you much input!
