[Nix-dev] NixOps, managing virtual hardware and network

[Wout Mertens]

Hi Sergey,

yup, NixOps fits the bill, but I'm not sure what you mean with being bound
to the host's physical adapter.
When you deploy virtualboxes with NixOps it gives the VM 2 interfaces: One
host-local and one on vboxnet0. If you want a different setup you'll have
to tweak nixops here:
https://github.com/NixOS/nixops/blob/41cf9ed862c13a4171c77e3494f9b7ca59a8adc0/nixops/backends/virtualbox.py#L363-L369

(if you do, make it configurable and send a PR please :-) )

As for specifying configuration of host and vboxen in one go, NixOps
doesn't do that. It only runs virtualboxes on localhost.
You can write a systemd service that starts the nixops network if you
like...

Another approach is to create a bunch of VMs manually and add them as
"None" type hosts to NixOps, then NixOps will just use them as-is.

Good luck!

Wout.
