VPC 2007 has 100% utilization?

Hi, I have a Vista host running a Vista guest in my VPC 2007 SP1. I have
this virtual machine to install betas etc.

However, I get 100% utilization and hangs my guest OS. I'm running this on
an IBM T60 laptop with a Centrino Duo.

I've read this is because VPC only runs on one processor. Any ideas or
hotfixes available? Thanks, Dave

The fact that it only utilizes one processor does not mean it monopolizes
that processor. In any case the T60 is dual core and you should not be
seeing more than 50% utilization due to the guest (100% of one core is 50%
of the cpu). There are a couple of settings you can change under the
Virtual PC options (File menu/Options/Performance on the Virtual PC
console). If the VPC console is minimized, right click on the icon in the
notification area and select Show VPC Console then select the File Menu.

It should also help if you enable hardware virtualization. I don't have it
and I'm not sure why because the Dell XPS 410 has it and I have XPS 600
which doesn't. I'm very envious of anyone with hardware virtualization and
can't wait for Dell to start selling machines with Hypervisor.

I have a Pentium 4 at 3.8GhZ with hyperthreading and I don't see any undue
utilization of just one cpu. I never have with VMWare Workstation 5.5
machines either.

Thanks, but none of those options seem to apply to my issue.

Hardware support does greatly speed up installations but once the vmadds are
installed I shouldn't think performance would differ much with or without
hardware assistance.

You can elimit the process of VirtualPC to one cpu use taskmanager of
host.Thou this is not a VirtualPC's option
