Well, just ran into a rather strange thing. I updated one of our proxmox 
servers, and after booting up the VMs they had no network access.

For historical reasons the switch port eth1 is connected to is 
configured rather special:
it uses VLAN Id 5 as untagged, but several other VLANs are tagged.

After upgrade I shut down all the VMs, rebooted proxmox server and 
started VMs again. It looked good until I tried to access the only VM 
that connects its vmbr with a tagged VLAN. That did not work, but using 
tcpdump I saw arp requests to the IP of this VM. Strangely, no answers.

So, to be up and running again I shut down all the VMs again and 
rebooted to use old kernel 2.6.32-11-pve again.

Any hint on what has changed regarding VLAN setup? I have to admit that 
I never really dug deeper into this subject, since it worked right out 
of the box when I initially configured it...


Best regards,

Stefan
