Ubuntu 20.04 host running multiple ubuntu guest servers

I'm trying to install a new 22.04.3 server, but the install insists on a network connection. Because I have non-standard MTU settings, I need to complete the install without a network, after which I can fix the MTU problem manually.

There doesn't seem to be an option to install without network.

I need to either set MTU in virt-install, or complete the install without any network. Can anyone suggest a way of doing either?

partially answering my own question...

during the network connections dialogue (VNC) if you click the HELP button top right, it gives an option to enter a shell. From there I added an <mtu: 1492> clause to the netplan yaml, then did netplan apply, and everything worked.

This is a temporary fix but allows the install to complete, after which I can edit netplan permanently via VNC.

It would still be nice to install completely without a network - not sure why you can't.
