That would depend on which of the host systems you choose and how much money you want to spend.
Not really but again it does depend on the host system. I would prefer to have the host outside the domain so that it is not looking for the domain on booting. VMware and Hyper-V support this. Shared NIC's work but spend the money and get a dedicated NIC for each VM if you can, way way better! If you use Hyper-V and purchase the Enterprise license you get one Physical machine license and 4 VM licenses, Data Center gets even better but with VMware you get no licenses.
