Hi,
Did some more test, I changed the network daemon from systemd-networkd
to NetworkManager (still use netplan), the 'vlan interface lost after
reboot' still there: reboot the os will lost the vlan interface, restart
the NM service could shows up the vlan interface. In the NM log, it
shows during the boot stage: manager: "(netplan-enc1000.1292) couldn't
create the device: no support for VLANs on interface enc1000 of type
Ethernet"
Here are some networkmanager service command output before and after 'restart nm service' as the comparison, and journalctl log file with operate timestamps:
>>>>>>>>>>>
journalctl -u NetworkManager > nm.log
timestamp: Jul 27 08:27 -> reboot the ubut os
timestamp: Jul 27 08:32 -> restart the nm service
>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>
run 'nmcli d' and 'nmcli c' before and after 'restart nm'
> before NM restart

I also compared the output of 'nmcli c show netplan-enc1000.1292' command before and after 'restart nm', found that the output of 'after the restart nm' not only include all the parameters in 'before the restart nm', and also plus the following parameters:

Status in Ubuntu on IBM z Systems:
Incomplete

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

VERSION_ID="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.
