MSFT doesn't officially support FreeBSD= , but I'm aware they support Linux on their virtual server. > It's typical for the cpu speed to very inside a virtual machine, VMware does this all the time, typically it's 0 ~ 100MHz off, but yours is way off... I did know the answer to this question but don't remember, sorry. try a google search for VMware and cpu speed or frequency.
