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

[mayijie]

Hi Frank,

Thanks for the investiaging.

Yes, Wei is my colleague, contacted with him and his trial was on a
similar system and almost same configuraiton of my testing this time.

And following you and Wei's last comments in 1996007, I reproduced the
same scenario w/ the only change is set the network interface from trunk
mode to access mode (leave the 'vlan id (optional)' field blank). In
this case, the IP addr did not lost. (Acturally, in the previous failed
case, the enc** interface was exist either, the lost interface was the
vlan interface, and the IP addr was assigned to the vlan in trunk mode,
so the IP addr was lost as well.)

This is the yaml configure file I use access mode adapter today:

*************************************************************
ubuntu at ibm:~$ cat /etc/netplan/00-installer-config.yaml
# This is the network config written by 'subiquity'
network:
  ethernets:
    enc1000:
      addresses:
      - 10.20.92.248/24
      gateway4: 10.20.92.254
      nameservers:
        addresses:
        - 10.20.0.2
  version: 2
********************************************************

>From the behavior, I understand your comment: "That let's me assume that
it's related to the current switch configuration.", but the strange is,
I installed ubuntu using trunk mode network from the older ubuntu
versions ago, the installation always successfully, ip assigned to the
vlan interface, no lost.

As a comparation, I installed an ubuntu 20.04 using trunk mode today,
the vlan interface remained after the installation, this issue (vlan
interface lost) seems only exist in 22.04 and 23.04.

I'll attach the install logs I tried today, hope they helps.

install 23.04 in access mode, success --> 2304-access-success-installer.tar
install 20.04 in truck mode, success --> 2004-trunk-success-installer.tar
install 23.04 in trunk mode, vlan interface lost --> please refer comment #7


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)

  "M[K[[0;1;31m*[0m[0;31m*    [0m] Job systemd-networkd-wait-online.se  tart running (1min 15s / no limit)

  Attached the operating system boot log.

  Thanks.
