[Bug 2022030] Re: vlan network device lost after the ubuntu 23.04 install complete

[mayijie]

Hi Frank,

Thank you very much for the repid and detailed reply, here is my answer:

1) Notice 'gateway4' vs 'routes ...'
>> Yes, the default installation using the 'gateway4', but there is a warning popuped 'gateway4 has been deprecated' when I tried 'netplan apply' to generate the vlan interface. For eliminate this warning, I change 'gateway4' to 'routes' manually and 'apply' again, the warning disappeared but the vlan interface still not there. 

2) Do you have an openvswitch (ovs) in your environment? If so, how is it setup?
>> I don't think so, the only thing I've added was a 0.0.1000 OSA device and a vlan based on 0.0.1000, the vlan interface covers the IP addr.

3) Have you done any other network related (re-)configurations?
>> No, except the manual update in step 1)

4) Can you please perform a default installation w/o ovs?
>> I'll try this, but from my previous success trials on 20.04, 22.04... there were no ovs configure.

5) Could you also share the output of:
$ lszdev --online

6) Is your system a DPM system?

7) Can you please share the exact settings that you've specified in your early network configuration step?
>> I'll attach the full interaction messages in this ticket while installing. (ubuntu-23.04-install-osm)

8) Also also what you have specified in the semi-graphical (subiquity) installer screen?
>> Please see the screen shot 1 and 2 (network in subiquity 1.png; network in subiquity 2.png)

9) Please would you also share the entire /var/log/installer folder?
>> Zipped the folder and will attach it soon. (install.tar)

10) And thank you for the 'systemd-networkd-wait-online' sharing, I'll
follow up your instruction.

Thanks~

Bug description:
  ubuntu at ibm:~$ cat /etc/os-release                                               
  PRETTY_NAME="Ubuntu 23.04"                                                      
  NAME="Ubuntu"

  VERSION="23.04 (Lunar Lobster)"

  System hardware: IBM LinuxONE

  Details:
  During the installation, I set up and actived a vlan device, after the installation, when I login the OS, the vlan device disappeared, I opened the '/etc/netplan/00-installer-config.yaml', double checked the config file, the vlan1300 is existing, and then when I 'netplan apply' to perform the configuration, an error message shows up, 

  "[?2004hubuntu at ibm:~$ 
  "sudo netplan apply
  "[?2004l
  "Cannot call openvswitch: ovsdb-server.service is not running.

  And during the boot stage, the systemd-networkd-wait-online.se tart
  running message shows a lot in the log, not sure these are related.

  "M[K[    [0;31m*[0;1;31m*[0m] Job systemd-networkd-wait-online.se  tart running (1min 11s / no limit)
