On a single k3s cluster using multus and the bridge CNI, the pods originally get set up fine and the networking functions as expected. When I reboot the host about ~80% of the time the pods fail to get scheduled and I see the following errors in the pod description.
The message DelegateAdd: cannot set "" interface name to "br0": validateIfName: interface name br0 already exists stands out to me as as it has an empty "" which seems to indicate to me that some values is not being picked up somewhere.
Any suggestions?
