[Openstack] Problem with neutron

My apologies, it looks like I scanned your original error message too quickly.

“Found no network for bridge br-int” means you need to run `xe network-create …`. AFAICT, xe network-create does not let you specify the bridge name. So, from the result of xe network-create, you need to invoke `ovs-vsctl add-br …` with the bridge name it specifies and reconfigure Nova/Neutron/OVS plugin to use that bridge as the integration bridge.

Hopefully that advice will get you further.

With OpenStack + XenServer is much more questions than should be. For example, what then is this - http://openvswitch.org/openstack/documentation/

Or Nicira NVP, where I can download it? Looks like it is now a part of VMware.

Yes , you must use Nicira NVP with XenServer

Hello,

Is this right tutorial<http://docs.openstack.org/havana/install-guide/install/apt/content/neutron-install-network-node.html> to install neutron in OpenStack with XenServer? In this section<http://docs.openstack.org/admin-guide-cloud/content/ch_networking.html#section_networking-intro> say's that OVS isn't supported in XenServer with neutron, is it right? So I must uninstall OVS and use this Nicira NVP?

Hello all,

I have problem with setting up neutron. I have latest havana realase and XenServer 6.2 as hypervisor.
I did all step-by-step from this tutorial http://docs.openstack.org/havana/install-guide/install/apt/content/neutron-install-network-node.html
All is going well, I can create network's, create router, create subnets, assign all that stuff... But when I start to create VM with selected network (demo-net or ext-net as describet in documentation), VM fail to build and erase from XenServer.
Error message - Exception: Found no network for bridge br-int

I looked in a lot of documentation, but can't find what I did wrong.

Thanks.
