Standard bridge and vSwitch on the same physical NIC?

[ksl28]

Hey,

I am using Open vSwitch on my PVE nodes, and wanted to integrate Veeams new backup solution to PVE.
But in the current version of Veeam, they do not support Open vSwitch - https://helpcenter.veeam.com/docs/vbproxmoxve/userguide/system_requirements.html?ver=1

My nodes only have 1 NIC, so i tried to use the physical NIC for both the Open vSwitch and the standard bridge (not sure it would work, but had to try).

auto lo
iface lo inet loopback

auto enp3s0
iface enp3s0 inet manual
        ovs_type OVSPort
        ovs_bridge vmbr0

auto vlan10
iface vlan10 inet static
        address 192.168.10.21/24
        gateway 192.168.10.1
        ovs_type OVSIntPort
        ovs_bridge vmbr0
        ovs_options tag=10


auto vmbr0
iface vmbr0 inet manual
        ovs_type OVSBridge
        ovs_ports enp3s0 vlan10

auto vmbr1
iface vmbr1 inet manual
        bridge_ports enp3s0
        bridge_stp off
        bridge_fd 0

iface wlp4s0 inet manual

When applying i get this error message:

ifreload -a
warning: vmbr1: apply bridge ports settings: cmd '/bin/ip -force -batch - [link set dev enp3s0 master vmbr1]' failed: returned 1 (RTNETLINK answers: Operation not supported
Command failed -:1
)

Is my config incorrect, or is it more likely that i am trying something unsupported here?

The issue might because the `enp3s0` is being used in both vmbr0 and vmbr1. If you have only one NIC you may follow the following config [0]
