Hi!
I've moved some VMs from Fedora 30 hosts to one running Debian Buster
(virsh dumpxml / define).
The VMs boot fine but their network is not working correctly. I am not sure
if their packaged version has different default settings that I am now
missing.
Even the VMs on the same bridge do not reach each other:
root@vm2021 ~ # ovs-vsctl show
32f20e3e-f937-4b42-b426-133e1422638c
Bridge "ovsbr39"
Port "ovsbr39"
Interface "ovsbr39"
type: internal
Port "bond0.39"
Interface "bond0.39"
Bridge "ovsbr40"
Port "ovsbr40"
Interface "ovsbr40"
type: internal
Port "vnet0"
tag: 388
Interface "vnet0"
Port "vnet1"
tag: 388
Interface "vnet1"
Port "bond0.40"
Interface "bond0.40"
ovs_version: "2.10.1"
For example, I can see ARP flow out of the VM -> VLAN -> Bridge -> Bond
VLAN (QinQ) -> HW-Switch.
The VM never receives a reply.

I am running the same setup on FC30 and it works fine, I tried to get the
same working with debian but I failed.
Any hints whats wrong here?
I've browsed all logs I found so far but there are no errors.
Thank you.
Kind regards
Kevin
