No 'PCI' bus found for device 'virtio-rng-pci'

[groulot]

I run NixOS 23.11 in a virtualbox VM.

Following the documentation, an error happens when trying to run my-microvm. If did
nix registry add microvm github:astro/microvm.nix, nix flake init -t microvm and then nix run .#my-microvm

$ nix run .#my-microvm warning: Git tree '/home/groulot/infra' is dirty qemu-system-x86_64: -device virtio-rng-pci: No 'PCI' bus found for device 'virtio-rng-pci'

Removing the example 9p share bellow in the flake fixes the error. The MicroVM starts and runs correctly:
shares = [ { proto = "9p"; tag = "ro-store"; source = "/nix/store"; mountPoint = "/nix/.ro-store"; } ];

Is there anything I missed that I should have done to make it work ?

Ouch, that is a consequence of disabling ACPI in c39a472 as required by #171.

Does the machine boot for you if you replace s/acpi=off/acpi=on/ in lib/runners/qemu.nix in your local checkout when running nix with --override-input microvm git+file:///.../microvm.nix?

Actually, breaking PCI is worse than #171 so I'm reverting that fix.
