[Xen-users] Another "how do i" question regarding networking and server consolidation...

[Charles Spirakis <bezaur@xxxxxxxxx>]

Hello --

I've been watching this mailing list and trying to find documentation
to do server consolidation using xen. Specifically:

I have:
Machine A at ip address x.y.z.10 and Machine B at ip address x.y.z.11

I want:

Xen domain 0 at ip address x.y.z.50, Domain U1 at ip x.y.z.10 and
Domain U2 at x.y.z.11 using (preferably) only one physical ethernet
NIC (in the old days there was ip aliasing to do this) such that (as
far as the rest of the network is concerned) they think there are
three machines, but there is really only the one physical Xen machine
with two guests. Is this possible with Xen and brctl?

And if so, anyone have any suggestions? Nearly everything I've read
assigns an ip address to the bridge and then does some form of
nat/route/vpn/vnet to the guest domains (to make the outside world
think there is only one machine). How do you make the outside world
think there are multiple machines?

Thanks!
