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

[mayijie]

Hi Lukas,

Thanks for the investigation, I followed your instruction, added the
"ignore-carrier: true", netplan apply and reboot, the vlan interface
shows up after reboot, cool~

But what I don't understand is the trunk mode adapter actually neither
cable disconnected, nor VM exist, and from my previous test, this case
only happened in ubut23.04, you can reference my comment #9.

So I did another installation ubut23.04 using another trunk adapter as
the backend adapter of vNic device, the vlan interface lost again, I
tried added the "ignore-carrier: true" in the yaml file, but this time,
no luchy.

Here the systemd-networkd.log read :

>From the log, it seems 'lost carrier' again, Hmm......

I compared the 10-netplan-enc1000.network, no difference I found from
the repaired one.

Here is the configure files:

'''
cat 10-netplan-enc1000.network
[?2004l
[Match]
Name=enc1000
 
[Network]
LinkLocalAddressing=ipv6
ConfigureWithoutCarrier=yes
VLAN=enc1000.1300

cat 10-netplan-enc1000.1300.network
[?2004l
[Match]
Name=enc1000.1300
 
[Network]
LinkLocalAddressing=ipv6

cat 10-netplan-enc1000.1300.netdev
[?2004l

Bug description:
  ubuntu at ibm:~$ cat /etc/os-release

  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.
