I have a Windows Server 2008 R2 on 64bit machine with 16 GB RAM and 2 x E5620 CPUs. This host running VMware 2.0.2 with 5 guests:

  • 3 x Windows 2008
  • 2 x Windows 2000 (after p2v - VMware convertor)

they all configured to use 1 CPU (not specified one.)

They are all using maximum of ~500 Mhz. For example, my Windows 2000 CPU reach 100% without effecting the host CPU, I mean when the guest CPU is 100% - it's using 284 Mhz of the host while the host CPU usage is 10% (generally, when I check at task manager).

Operating system use uniprocess without any hidden devices at device manager.

Any idea?

Why VMWARE SERVER not increasing the CPU resources for this Guest? there is free resources on the host and i didn't set such limit. – user121066 May 15 '12 at 9:21

According to the VMware Server documentation Windows Server 2008 R2 is not a supported operating system. It's not surprising that you're experiencing performance issues.

You shouldn't be using VMware Server anywhere. It was end of general support on 6/30/2011. It's dead, let it die. If you have Windows Server 2008 R2 and need to run Windows on the host for some reason, consider the using Hyper-V role. If you can use a bare-metal hypervisor, I'd recommend using the standalone Hyper-V Server of the free VMware ESXi.
