Cannot launch Ubuntu 22.04 multipass on my Ubuntu 24.04 machine

**Describe the bug**
I am trying to launch Ubuntu 22.04 multipass on my Ubuntu 24.04 machine. But I must be doing something horribly wrong as it just hangs.

**To Reproduce**
How, and what happened?
1. multipass start jammy -vvvv
1.

**Expected behavior**
I expect it to start quickly and give me a shell

**Logs**

- `multipass version`

multipassd 1.15.0

**Additional context**
Add any other context about the problem here.

I tried to watch the network, but it seems there is no bootp server running. My local network has one on 192.168.4.1 but I'm not sure if multipass is trying to use that or its own?

Start by running `multipass start jammy -vvvv` with the reported Ubuntu 24.04, Multipass 1.15.0, and qemu configuration. Read the attached log and inspect the DHCP requests on `mpqemubr0`; completion means the jammy instance launches successfully and provides a shell.
