Hello Proxmox,

Hopefully I've posted this in the correct forum.

I'm interested in better understanding Open vSwitch within our environment. I'm running a cluster of Proxmox Hosts and will be connecting them to Ceph. All Ceph and Proxmox servers will run Proxmox 4.1 and will be in the same cluster.

I use GUI to create OVS Bridge in pve1 and pve2, such as :

upload_2016-4-13_11-15-5.png

But by ping, pve1 and pve2 can't communicate with each other, what should I do?

thanks very much~!

PS ：Before I use the eth3 nic to create Linux Bridge of communication is normal,so I'm sure eth3 is to be able to normal communication.
 
Thanks aychprox！

The /etc/network/interfaces configuration :
root@pve1:~# more /etc/network/interfaces
auto lo
iface lo inet loopback

iface eth1 inet manual
iface eth2 inet manual

allow-vmbr1 eth3
iface eth3 inet manual
ovs_type OVSPort
ovs_bridge vmbr1
ovs_options tag=102

allow-ovs vmbr1
auto vmbr1

netmask 255.255.255.0
ovs_type OVSBridge
ovs_ports eth3 vlan102

ovs_extra set interface ${IFACE} external-ids:iface-id=$(hostname -s)-${IFACE}-vif

pve1 and pve2 still can't communication.

Hi,
do you use the right openvswitch-package? the normal debian-one has issues with vlan-tagging. If you have the pve-repositorys enabled (enterprise or no-subsription) you get newer ones.

And don't use an IP on the brigde... use someting like this (and tag vlan 102 on the switch side):
Code: 
auto lo
iface lo inet loopback
iface eth0 inet manual
iface eth1 inet manual
iface eth2 inet manual

auto vmbr1
iface vmbr1 inet manual
   ovs_type OVSBridge
   ovs_ports eth3 vlan102


auto eth3
allow-vmbr1 eth3
iface eth3 inet manual
   ovs_type OVSPort
   ovs_bridge vmbr1
   ovs_options vlan_mode=native-untagged
   ovs_options tag=1

allow-vmbr1 vlan102
iface vlan102 inet static
   ovs_type OVSIntPort
  ovs_bridge vmbr1
   address 10.10.10.11
   netmask 255.255.255.0
   ovs_options tag=102
   ovs_extra set interface ${IFACE} external-ids:iface-id=$(hostname -s)-${IFACE}-vif
