Hi,

I'm thinking of getting a new server, and I'm wondering about the AMD
 2000 series processor with support for hardware virtualisation. But
as I only ever use Linux, is this much of an issue?  Everything I
have read seems to say HVM is good for running unmodified guest OS's
- like windows. But I only need Linux which is already ported to xen,
so do I really need hardware virtualisation?  There must be other
benefits to using it? But what are they?

Even if you only run Linux DomUs, if the cost difference between aHVM-capable vs a non-HVM CPU is small enough, I'd go with theHVM-capable CPU. You know, just in case things change 2 years from nowand you need the HVM capabilities for some odd corner case.


But then I believe in hedging bets whenever possible.
