Hi 'liwbj',
I see some advanced configurations like openvswitch, special routes, etc.
Usually the installer is supposed to deal with the initial and more basic setup,
and it's recommended to perform further and more advanced configurations after the installation got completed.

So if you follow the steps here:
https://ubuntu.com/server/docs/install/s390x-lpar
especially the basic network configuration for a VLAN environment - search for "Proceed with the interactive network configuration, here in this case in a VLAN environment"
and then just accept the network config in the subiquity network config screen as it is,
your system should come up after the post-install reboot.

Please could you confirm this?

If that's the case I recommend to create a backup of the existing (basic) netplan yaml file:
/etc/netplan/00-installer-config.yaml
perform your specific modifications
verify your netplan modifications using 'dryrun':
sudo netplan apply --dryrun
and if no problems are reported, apply it finally with re-running the command, just w/o 'dryrun':
sudo netplan apply

(And yes, always use the latest point release of an Ubuntu LTS, like you did here by using 'ubuntu-22.04.1-live-server-s390x.iso'.)
