All,

I'm currently thinking of buiding a xen firewall and extra functions in it.

I'm wordering is It will be  an advantage/disadvantage or no differance
when i run DomU on a (non) Pacifica/van der Pool aware CPU.

Xen domU's running in hvm mode have several differences to non-hvm domU's.
Mainly I can think of performance (I've heard people reporting bad
performanve in hvm due to the disk IO emulation and the lack of (live)
migration (not sure if save/resatore also don'tr work right now)
functionality.
I don't know if any of those is especially important in your case.
