I don't know, but here's a list of the servers and their CPU types
so you can work it out.
Host | CPU
barbar | Xeon L5420
corona | Xeon 3060
curacao | Xeon 5148
dunkel | Xeon L5410
faustino | Xeon L5410
kahlua | Opteron 2212 HE
kwak | Opteron 2212 HE
mumm | Xeon L5410
obstler | Opteron 2214 HE
Next one will be
urquell | Xeon E5520
Info on those
Xeon L5410, L5420:
Opteron 2212 HE, 2214 HE:

or are VM's fairly tightly coupled with the host?
At the moment it can't happen easily (i.e. without your knowledge)
because the storage is still local to each server, so moving a VPS
requires it to shut down and have its filesystem copied to the
You might choose for your VPS to be moved if you ask for more RAM
and/or disk and there isn't enough available on the host you're

I think it would be a really bad idea to make your kernel/userland
not support all of the above CPUs, but I don't think that would be
very easy to do since they all have very similar features. As far as
I can see the lowest common denominator is "MMX, SSE, SSE2, SSE3".
