I am new to NixOS and I have been using Vagrant for a long time. I am looking to build several VMs in a new NixOS box but although I can create a VM with virt-manager I would like to know if NixOS has a module where I can configure VMs like in Vagrant.
I’m having great success with nixops at the moment. It has a lib-virt backend.
It might be exactly what you need. However it can only deploy nixos machines.
How were you using vagrant before?
