Cannot deploy nixops net

Help
1

With the following deploy.nix:

rec{
  node1=(import ./node.nix)//{
    deplyment.targetEnv="virtualbox";
    deployment.virtualbox.memorySize = 1024; # megabytes
    deployment.virtualbox.vcpu = 2; # number of cpus
  };
  node2=node1;
  node3=node1;
}

I get the following error on nixops deploy ./deploy.nix -d test --debug:

Doesn’t nixops prepare dns and ssh keys automatically?

I think nixops uses /etc/hosts for this, there is no dns involved.

Don’t know why it is not able to connect to the node. According to the manual you need to set up network configuration for virtualbox properly.

For the details you have to look at nixops manual, but if I remember correctly, I think you can not use bridged network, and also there must be a vnet0 interface or something like that.

virtualbox needs to provide the ip address via it’s dhcp service.
