Force VM rebuild #47

Closed onny closed 3 years ago

onny commented 3 years ago

Hey, I guess NixOS is caching somehow the state of a VM and only applies changes if you run it again. How can I force a rebuild or delete the KVM images manually?

Regards Jonas

For clarification why I struggle with this issue: I'm using nixos-shell to test a module and it works great so far! The module / service is a web app which creates a Mysql database and uses it. To test it correctly, I want to start the module again with a fresh and clean database setup, without retaining the old entries.

You can reset your virtual machine by deleting nixos.qcow2 in the same directory.

Oh nice thank you. Already tried that but somehow missed it. nixos-shell is so fast that I couldn't believe it ;)
