Hello,
Can you give some more details please ? Best Regards, From: Reid Price [mailto:rpr...@nicira.com] Sent: Thursday, September 19, 2013 11:51 PM To: Faisal Ali Cc: Alexandru Coseru; discuss@openvswitch.org Subject: Re: [ovs-discuss] Openvswitch configuration persistence Hi guys [+list], You might find that you have unexpected behavior down the road with that tactic. I would perhaps suggest an approach where you set a value (using xapi) for the PIF's other-config, and then run your own script (perhaps on bootup) that finds PIF and does configuration based upon that field. Otherwise you are likely to cause Xenserver to freak out at some point, or to have stale network configuration floating around. -Reid On Thu, Sep 19, 2013 at 10:46 AM, Faisal Ali <justhu...@gmail.com> wrote: Yes, I found that on Xenserver 6.2 the openvswitch startup script resets the ovs configuration. With my limited knowledge of scripting I managed to find a particular lines and comment them out.

We want to use openvswitch to a configure a host with 2 nic with STP ON (for switch redundacy).
