Opteron 1210 can be used with Hypervisor?

12/03/2008, 14h31

I'm thinking about a new hardware buy for my personal use - DELL T105
Opteron 1210
The AMD 1210 have AMD-V and is a Stepping F3 processor

Can I use with Hypervisor? I't's a good choice?

13/03/2008, 14h02

I Have a VS Server with 2 VMs (IIS and SQL)

Sometimes, a huge proccess runs on SQL and CPU of the VM goes 90%-95% and on
the Physical machine the CPU goes 35%, but only in ONE of the processors.

Is a DELL Quad-Core, and proc0 goes 35% and proc1-3 stays in 1%-Idle

Why? VS it is not a Multi-Threading app?

13/03/2008, 16h26

VS provides only a single CPU to a VM.

Yes, it should work. Good choice? Well, I think most folks today would say
that the Intel CPUs have a performance advantage over AMD in most
situations, especially in the single socket environment. But that being
said, the difference isn't huge, and the design and implementation of the
I/O subsystem is likely to have a far greater impact on your VM performance
than the difference between an Intel and an AMD processor.

If so, where is the advantage on MultiCore/SMP systems using VM Server?

I think this limitation in a different way: My knowledge is that even in MP
machines, the VM will only "see" one CPU. Ok, we both agree on that.

But why the VM Server proccess can use only a single CPU (CPU0) on a
Quad-Core machine? Why VS can't balance the use among all 4 logical
proccessors of the physical machine?

In my scenario, if the another VM begins to "eat" (use ) CPU too, it will
use CPU1, CPU2 or CPU3 of the physical machine?

It's for my personal use, studying, etc.
I think will do the job (at least i hope) to use Win2008 + Hypervisor on it

A single VM will only use 1 CPU/core. If you have, say 3 VMs, you
take full advantage of a quad-core system, 1 core for the host, 3
cores, one each for the 3 VMs.

Correct.

Mainly because it involves a lot of complex programming.

Each VM will see 1 cpu/core. If you're running less VMs than you have
CPUs/cores each VM will have it's own cpu/core.

Virtual Server will load balance between the available CPUs.
