Virtual Server 2005 R2 CPU usage

Hi Guys

Hope someone can help me with this.

I seam to be getting mixed message from Forums and MS products support.

I have windows 2k3 standard with Virtual server 2005 R2 installed on Duel Quad core system.

MS products support tells me that Virtual server 2005 R2 enterpise supports upto 32 CPU but will be limited to 4 CPU as it is running on W2k3 Standard. Also that there is no different version of Virtual server 2005 R2 or Virtual server 2005 R2 Enterprise.

The forums I read say that Virtual server 2005 R2 is limited to one CPU and if that is install on a duel Quad core system, (Like my system.) Then you are limited to 1 core. Thus only getting 12.5% of the CPUs.

When I look at taskmanger on the VM system it only shows 1 CPU, and system info shows that to be a 1.66 ghz. (speed of 1 core of my duel quad core.)

I ran a CPU test using some freeware software that returned a speed of 1.66 ghz. This test is likly invalid as I am sure the software did not take into account multicore processors.

Also if I look at VM administrator I can only set the VM to utalize a max of 12.5% of the CPUs.

So I guess I have 3 questions
1) Is Virtual server 2005 r2 limited to 1 core
2) Dose Virtual server 2005 r2 become the enterpise version if install on a W2k3 enterpise server, and then let you access 4 CPUs.
3) Is there a test I can run to confirm the real performance of the Virtual Machine.

Thanks for your time.
