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.
