Hello,
If memory serves me correctly Intel's VT-X technology supports only one
virtual cpu. Even if you have 4 cores the guest OS will only see one of
them. Multiprocessor Windows would be pointless.
A modified xen guest would see multiple cpus.

Every time "hvmloader" comes up to load a VM, it shows cpu=1 as
detected, no matter what number you give in .hvm configuration file. I
have vcpus=2 and cpus = "2-4" in my .hvm file!
Any idea why is this? Or Am I missing anything?
I am guessing due to this I am not able to run the un-modified
"Multiprocessor" Windows.
Any help would be appreciated.
Thanks R
These are the details of my configuration
I am having a server with 2 dual core XEON with VT-x enabled on it.
