Hello

I have 3 VM running in proxmox. Ubuntu, Windows and Home assistant OS.

After the upgrade to pve9, Ubuntu and windows got the ip address (no VLAN tag for these two), but HA OS dont get ip address (VLAN tag present). I get error like this

I removed the VLAN tag, then it works fine.

Before or after the update i didnt change anything in the networks. It looks like this.

Any idea what could be the issue here?
 
How does the VM get the IP address? Via DHCP?
How does the network configuration inside the VM look like?

Can you post the config of the HA VM?

Code:
qm config <vmid>

Can you provide the output of the status command that is visible on the screenshot?

I think i set it up with DHCP.

Code:
root@arifroni:~# qm config 210
agent: 1
bios: ovmf
boot: order=scsi0

what do you mean by "Can you provide the output of the status command that is visible on the screenshot?"?
which command output?
 
Code:
systemctl status NetworkManager-wait-online.service

Can you post the Network Configuration of the VM as well?
 
Did you execute that on the host or inside the HA VM?
 
Please execute it inside the VM if possible, where the problem actually occurs.
 
problem solved.
It turns out, it has nothing to do with pve9 upgrade. I changed my switch ports in unifi system at the same time of upgrade. and new switch port had VLAN tag disabled. :rolleyes:
