Hi,
Just installed proxmox 5.3.2 on a brand new host.
Added an OVS Bridge vmbr1 :
Code: 
auto vmbr1
iface vmbr1 inet manual
        ovs_type OVSBridge
        ovs_ports eno4

Added a windows VM to it and tagged its network VLAN to 1066:
Code: 
ovs-vsctl show
afb91225-e477-449b-8b92-1325821ef6cf
    Bridge "vmbr1"
        Port "tap100i0"
            tag: 1066
            Interface "tap100i0"
        Port "vmbr1"
            Interface "vmbr1"
                type: internal
        Port "eno4"
            Interface "eno4"
    ovs_version: "2.6.2"

If i run ovs-vsctl list interface, the vmbr1 bridge does not seem to be transmitting traffic over the physical NIC:
Code: 
name                : "eno4"
ofport              : 1
ofport_request      : []
options             : {}
other_config        : {}
statistics          : {collisions=0, rx_bytes=0, rx_crc_err=0, rx_dropped=0, rx_errors=0, rx_frame_err=0, rx_over_err=0, rx_packets=0, tx_bytes=0, tx_dropped=0, tx_errors=0, tx_packets=0}

If I ping from the windows machine to another machine, i can see part of the request onthe vmbr1 (ARP, Request who-has 10.0.72.75 tell 10.0.72.71, length 28) but nothing else.

What am I missing to make this configuration work?

Thanks

# If you want to manage parts of the network configuration manually,

Try this:
Code: 
auto lo
iface lo inet loopback

iface eno1 inet manual
iface eno2 inet manual
iface eno3 inet manual

allow-ovs vmbr1
allow-vmbr1 eno4
iface eno4 inet manual
       ovs_type OVSPort
       ovs_bridge vmbr1
       ovs_options tag=1 vlan_mode=native-untagged
#If you have untagged traffic, set vlan tag for native vlan

Hi,

I've added the proxmox repository and have openvswitch-switch v2.7 installed now instead of 2.6.2 and allow-ovs is accepted as a command now.

VMs still do not have network access. ovs-vsctl commands do show that vmbr1 is up and running. I also see counters going up and can run tcpdumps on the vmbr1 interface and see the ARP requests.

Thanks, fixed that. Does it matter though? If I understand correctly the doc, OVS should be able to use the VM tag information and the OVSIntPort are only for host usage if I need the host to have an IP on that VLAN?

How do I get the VM configuration command line?
