Add this to your test config:

interactive.~~nodes~~.~~machine = {~~

interactive.sshBackdoor.enable = true;

~~services.openssh = {~~

enable = true;

~~settings = {~~

~~PermitRootLogin = "yes";~~

~~PermitEmptyPasswords = "yes";~~

};

~~security.pam.services.sshd.allowNullPassword = true;~~

~~virtualisation.forwardPorts = [~~

~~{ from = "host"; host.port = 2000; guest.port = 22; }~~

];

};

Now you can connect to this VM via

Now you can connect to this VM via (on linux):

ssh root~~@localhost -p 2000~~

ssh -o User=root vsock/3

If you are on MacOS or have multiple VMs look at the shell output that do run the interactive tests:
