Hi Frank, The XenAPI calls related to PIFs, VIFs, and Networks serve the same purpose no matter whether the linux bridging or the open vswitch backend is in use. These calls are used to create and configure (virtual) interfaces, bridges/vswitches and networks.
The XenAPI does not do anything with OpenFlow. Everything OpenFlow related is done by the vswitch controller, which talks directly to the vswitches inside the hosts in your pool. ACL rules, for example, can be defined in the web GUI of the controller.

Hi Rob: Cloud you kindly point me which part of API is responsible for flow controller? I searched java doc of FP1 beta API, only got "setVswitchController" and "getVswitchController", not see OpenFlow relevant API. Thank you very much.

This controller uses OpenFlow for setting up ACL rules etc, and another, Open vSwitch specific, protocol to create GRE tunnel ports remotely.

What "controller" means here? is it an openflow controller or controller made by xensource? as I know, openflow standard has no definition for creating a GRE tunnel. thank you On 12/12/2010 08:11 AM, Rob Hoes wrote: Hi Frank, You need to connect the Open vSwitch Controller that came with XS 5.6 FP1 beta to your pool. The controller sees the tunnels that you create by the xe commands (as you did), and will create the GRE ports on the vSwitches for you.

I already know how to do these by open vswitch, I just want to use xe command do same things. than kyou. -- Frank Zhang Cloud.com INC _______________________________________________ Xen-users mailing list [email protected]<mailto:[email protected]> http://lists.xensource.com/xen-users -- Frank Zhang Cloud.com INC -- Frank Zhang Cloud.com INC
