only use a single processor license (Microsoft allows this on a physical
dual core processor), but I'm curious as to how the processors show up
in a DomU, whether they will be seen a 2 single cores or 1 dual core...

You can limit how many cores which will show up in /proc/cpuinfo with the "vcpus" parameter in the domU configuration file.
