It is possible to slow down the virtual pc machine in Win7 (by reduce CPU etc.)

Question

I am trying to get a slow machine with IE8 to test for some customers. It is possible to slow down the virtual pc machine provided by MS? I did only find how to reduce RAM but not CPU.

Answer 1

In options, you can choose to divide CPU time equally among all VPC instances, versus runing the active VPC at maximum speed.

Answer 2

No, this is not possible due to the way virtual machines work. As the virtual machines runs directly on the processor, you cannot slow that down. Your only option is to run on a virtual machine that does processor emulation.

Answer 3

VirtualBox from Oracle does what you want. In the main interface, click Settings > System > Processor and set the Execution Cap to (say) 50%. Works nicely, except that the entire VM slows down (not just a specific application like IE).
