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

[mayijie]

In the log, in the boot stage after reboot, it shows the enc1000 link up
and then link down due to lost carrier, but I'm sure the back end
adapter was good, this case just occurred in ubut 23.04 in trunk mode
adapter.

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)

  Attached the operating system boot log.
