How would i go about creating multiple vm's on localhost

I've been attempting to use xHyperV.
I've tried the multiple nodes approach.
That obviously has the flaw that it's trying to create the vm on a vm that does not exist.

I've tried 1..VmCount | %{ Create VHD, Create VM }.

That has the issue that the vhd/vm object already exist when it tries the 2nd time.

I'm out of ideas here.
