Describe the bug

The apt-get install output sometimes breaks the NixOS test runner. I think it's related to the apt menu. The current (terrible) workaround consists in redirecting the apt-get output to a file.

I don't have a minimal reproducer yet.

Is your feature request related to a problem? Please describe.

The current solution supports a single VM.

For scenarios where integration tests span across multiple VMs, it would be helpful to spin them all up inside the test environment and have a network layer over which they can communicate with each other.

Describe the solution you'd like

Something similar to the NixOS VM tests where each instance is keyed by its hostname.

Describe alternatives you've considered

Additional context

Describe the bug

We can access the store 9p mount just fine from the host, however, the systemd services cannot access it.

When the service tries to access the mount, this error message pops out in the journal:

9pnet_virtio: no channels available for device nix-store

I tried these recommandations https://superuser.com/questions/1317119/qemu-share-folder-9pnet-virtio-no-channels-available-for-device . No luck.

I tried:

• Disabling SELinux.
• Set ProtectSystem to false

It feels like a weird systemd/9p interaction to me. I searched the systemd bug tracker, there's no related issue, opened or close.

This issue does not manifest in Ubuntu or Debian. They're using older systemd versions.

We probably should try to find a minimal reproducer and poke upstream with that.

For now, the image.json files have been mostly generated manually. We should automate this process for Ubuntu, Debian and Fedora.
