RTNETLINK answers: Operation not supported

[devilrox]

Hi all,

This morning i've activated the proxmox firewall on our server and found a strange problem i can't figure out at the moment, after hours searching on google i try to ask you guys.

VM and all the server is working fine, network is ok etc..
i've activated the firewall flag on the network card of a vm, stopped and started again and got this error:

Running as unit 1001.scope.
RTNETLINK answers: Operation not supported
can't create interface fwln1001i0

i've also tried with on other vm, same result.

if i remove the firewall flag on the network card boot normally, the proxmox installation is not at the last version and has very big uptime now: 418days so i don't know if a reboot could help but i would like to avoid it.

Anyone had this problem and know how to fix it?

Thank you
Marco

Just add an information:

The server where i'm having the issue has a ovh kernel (damn...) i've done the same on an second proxmox server running vanilla kernel and worked fine.

Could be something related to this?

Thank you again
