Thanks, I'll test it today. 


Here some notes about /etc/network/interface management with their provide script: 

if we defined this kind of openswitch with bond0 or port: 

allow-ovs br0 
iface br0 inet manual 
ovs_type OVSBridge 
ovs_ports eth0 


we need to defined eth0 like this 

allow-br0 eth0 
iface eth0 inet manual 
ovs_bridge br0 
ovs_type OVSPort 


But if we do this, we can't defined the eth0 in the classic way. 
So I think it's strange.. 

could be better to be able to do 

allow-ovs br0 
iface br0 inet manual 
ovs_type OVSBridge 
# ovs_ports eth0 
bridge_ports eth0 



in ifupdown.sh: 

OVSBridge) 
ovs_vsctl -- --may-exist add-br "${IFACE}" ${IF_OVS_OPTIONS}\ 
${OVS_EXTRA+-- $OVS_EXTRA} 

if [ ! -z "${IF_OVS_PORTS}" ]; then 
ifup --allow="${IFACE}" ${IF_OVS_PORTS} 
fi 

+ if [ ! -z "${IF_BRIDGE_PORTS}" ]; then 
+ ovs_vsctl -- --may-exist add-port "${IFACE}" "${IF_LINUX_PORTS}" 
+ fi 



Or maybe can we create from statch a script, to keep syntax almost same than classic configuration. 



Another important thing: 

openvswitch keep the configuration in /var/lib/openvswitch/conf.db (json database). 

But if we remove/change configuration in /etc/network/interfaces, on reboot it doesn't change the conf.db. 
So, maybe it's better to delete the conf.db on reboot, and recreate it from /etc/network/interfaces on start.

I just created a new git repository so that we can test with latest code: 

https://git.proxmox.com/?p=openvswitch.git;a=summary 

Pre-compiled packages can be found in the pvetest repository.
