well you can telnet to it, so I guess it's OK

Hmm mine doesn't either. How about that? (I wonder when that 
changed, or maybe it's always been that way and I've never 
noticed.)

It looks like you've done all the right things. I assume 
you're going to have the same problem with LVS-DR if adding 
the VIP to lo:0 kills the network.

I would assume there's something wrong with Xen at this 
stage. I don't know how many people are using virtualised 
servers - there's got to be a few and we aren't hearing 
anyone having problems. The only one so far is

I'm stumped sorry.
