How to use multiple cores on virtual pc ?

I want to run VirtualPC 2007 on my system. Is there a virtual pc software that use multi core processors and allow processing power allocation to different virtual machines ?

Thanks

You can try on VMware ESX Server to utilize more than 2 processors in a virtual session. Or you can also try on Microsoft' Windows 2008 Server.

The main purpose of Virtual PC is to allow the user to run multiple guest machines on one real host machine. This is not hard to accomplish, but you must remember that each guest operating system that you plan to install and use requires a lot of disk space, depending on the type of operating system you plan to install.
