Hi Xavier,

This is actually a very good catch. We do advertise the MAC address because in time between
instance guest tools report the IP address to VSPhere we don't know what the real IP address

How about this:

  <address type="mac">3c:97:0e:1b:3b:82</address>
  <address type="ipv4"></address>

I mean we can just keep reporting the MAC address. Also I think we can do the same
for RHEV-M and for the OpenStack.

I can't see anything that we could possibly break with this, because it is just addition.
But might be I'm wrong :-)
