If you set vcpus=4, Microsoft Windows will see 4 x single core CPUs.  Virtual CPUs are (to my knowledge) always passed through as single core CPUs.

A few Microsoft products are licensed per Processor, where a Processor
can have up to 4 cores.

If I set up a HVM machine with vcpus=4 on a quad core processor, how
will the operating system see these? As a single Processor with 4 cores,
or something else?

Thanks

James
