Network is not coming up automatically after Upgrade 3.4->4.2

[nasenmann72]

Hi,

yesterday I have upgraded one single PVE node from 3.4 to 4.2 according to the upgrade guide in the Proxmox wiki. All went well except that the network is not coming up when booting. I have to manually restart it (systemctl start networking.service) then all interfaces come up. Can anyone give me a hint what could have gone wrong?

In syslog there are those messages:

Hi,

please purge the openvswitch package and install it new.

Thanks,
I will try to reboot the machine this night to see if it has solved the issue.

Hi Wolfgang,
thanks, purging and reinstalling openvswitch packages did the job.

Best regards
