waifud

A few tools to help me manage and run virtual machines across a homelab cluster.

waifud was made for my own personal use and I do not expect it to be very useful outside that context. If you do want to run this on your infrastructure anyways, please contact me.

THIS IS EXPERIMENTAL! USE IT AT YOUR OWN PERIL!

TODO(Xe): Link to blogpost on the design/implementation once it is a thing.
