Re: [Xen-users] VMX Extensions

Hey Thorolf,

Thanks for the info.. I think we'll be going with the 930's for our config.

I'll post back our benchmarks once we have them.

If you're using unmodified guest you have to get new hardware and the price for a dual-core is not much higher than for a single-core-system with a Pentium 4 with Intel-VT.

But mostly it depends on how many VMs you want to run on the server, but I would get always more than one CPU-core today!

>the purchases TODAY, and we're limited to Dell Hardware..
Personaly I don't like Dell-hardware at all, the ones I know where in comparison with the IBMs I knew really bad. But possibly I'll get a Dell-system with Intel-VT too, either a Dimension 9150 Superior Spezial or a Precision 380 Essential which both come with an Pentium D 930 and should be VT-compatible!

But these PCs are no servers, they are just for a cheap testing-system, if such a system should go for production I would get an IBM server with Xeon/VT or Opteron/Pacifica (which are both not yet available)!

This will be my choice for a new system for prototyping that should support unmodified HVM-guests!

Xeons are not yet available with Intel-VT, the Bensley-systems should be available in at about one month!
