Xen users - Aug 2013 - Regarding Openvswitch suppotrs Xen 4..2.1

Hi,

As I see blogs or websites the openvswitch is support XCP and Xenserver.
But to support opensource Xen 4.2.1 what should be configure and how to
interface with openflow .
I have tried using vif-openswitch network script for bridging, while
 adding datapath using ovs-dpctl add-dp xenbr0 it is added but ovs-dpctl
dump-flows xenbr0 it is getting
ovs-dpctl: opening datapath (No such device). Can you suggest any
configuration for openflow with openvswitch.

With Regards
Prapulla Kumar R

Note that OVS support was only added upstream in 4.3. I cannot guarantee
that other fixes are not required for it to work on 4.2.x (e.g. I recall
some hotplug related changes which were needed for clean teardown, but
not if they are in 4.2.x or not).

If you want OVS support you would be best advised to switch to Xen 4.3

Did you configure the host networking as described in

?
