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

[Frank Heimes]

Hello mayijie,
thanks for the additional info and data.

Based on this I tried to recreate on a local DPM system here (in a
configuration that is as close as possible), but was not able - in other
words: it worked fine for me.

I stayed with gateway4, since it's just a warning, no need to do
anything (it's on us/Canonical to change this before the deprecation
warning will turn into 'no longer supported').

I also attached multiple NICs, some that are connected and have a link
and others that are not (to force the timeout during the install), but
also this didn't cause any issues.

(see attached attempt to recreate)

But your case reminds me about LP#1996007.
May I ask if you are working on the same system and environment than "liwbj at cn.ibm.com"?

We did quite some investigations and I am pretty sure that this (his and
maybe your) issue is based on the configuration of that local system.

Another indicator is that nobody else ever reported this - but it seems
to be in that env. the same for 22.04 and 23.04.

  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)

  Attached the operating system boot log.

  Thanks.
