RE: [Xen-users] How to use "xe tunnel-create" to create GRE tunnel?

[Rob Hoes <Rob.Hoes@xxxxxxxxxx>]

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.

 

Cheers,

Rob

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.

The controller I am talking about is part of XS 5.6 FP1 (Advanced Edition or higher), which is released by Citrix very soon, and was also included in the beta. 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

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.

Regards,

Rob

  Hi,

     In XenServer5.6 FP1 beta, I have switched default bridge to

open

vswitch, I wonder how to use "xe tunnel-create" to create a GRE

tunnel.

my commands:

xe tunnel-create pif-uuid=eth0_uuid

network-uuid=network_created_by_xe_network_create

then I got an uuid which is "access-PIF" of output from "xe tunnel-

list".

what should I do next? how to set remote_ip and GRE type and GRE key?

I already know how to do these by open vswitch, I just want to use

xe

command do same things.

than kyou.
