I wanted to automate my linux VM deployment on my Hyper-V based lab infrastructure. One small flaw: while DHCP does automatically update DNS, it does *not* do too much when your VM is named "localhost". I wanted to make the fedora deployment completely automated... which it is after I wrote a kickstart, except you can't get into the new box because you can't find its IP address.
I wrote a small tool to deal with this issue:

You want the variable `VirtualMachineName` in `/var/lib/hyperv/.kvp_pool_3`.
Documentation that took way too long to find:
