I want to build a new computer system that features dual processors, a lot of memory, and is able to run Xen virtualization. Install Fedora and Xen as the host on such a machine, and then start running a variety of other operating systems as virtual machines.
What dual processor hardware configurations work well with Xen? For example will any Supermicro brand dual processor motherboard be hardware compatible with Xen? I am thinking of Supermicro boards with Xeon processors. Or is there a better brand of motherboard?
Thanks

I am using asus rs100, its cheap and works very well.
I have some machines running since 3 years, with 100% uptime.

With 2-4-6 core CPUs out there, do you really need that level of cost and complexity? I run an x58 ASUS Sabertooth board with i7-950 CPU and 24GB ram, and it seems up to most of what I even plan to do. With eight threads I can handle lots of VMs, although I am running most with KVM rather than xen. Newer boards will go to six (hyperthreaded) cores, but I believe only support four sticks of mempry.

Anyone have experience using Shuttle XPC or similar Mini ITX? I wanna have powerful machine and would be nice if it's quite. Regards,

I just built a new system to replace my main one which died, and the one I built runs really quiet and is pretty powerful:

Ooops, I accidentally replied only to Bill. Here is what I sent to him.
I recently started working with a dual processor workstation bought from Dell. My role is to support the hardware and get the software installed. It is set up with two, Xeon E5645 6-core processors. Based on only about 2 hours of working with it -- they seem to make a significant speed difference difference. This is with a mere 12 Gb of registered DDR3 memory (6 Gb per processor.) Unfortunately we can only do 12 Gb for now, we were hitting the budget limit. I have a question out to my customer asking about the actual experience with applications. My impression is there is a lot more speed.
I have a second person who really maxes out cpu performance and I think that person needs to go beyond the single processor stage. Maybe it is time for multiple processors, each with loads of cache and cores, and some serious memory.
