Re: Compute node with xenserver
There appear to be conflicting (or partially incomplete) guides for this at http://devstack.org/guides/multinode-lab.html and at http://devstack.org/localrc.html. There is full documentation on the stack script and which settings you need to consider for multi host (search for multi) at http://devstack.org/stack.sh.html.
We set the following variables on the slave to enable a multi-host setup:
PUB_IP=<This node public network IP>
VM_IP=<This node VM network IP>
Of course, on the master MULTI_HOST also needs to be set to true.
Note that the hostnames for the computes need to be unique, and so if you already have a compute called "DevStackOSDomU" (the default) then you'll have to change GUEST_NAME in localrc and the hostname for the second compute node. This is also true if you want to add further compute nodes.

Thanks for your reply Bob. Ok now i have a xenserver with a domU. I have followed this doc : https://github.com/openstack-dev/devstack/blob/master/tools/xen/README.md
But now how to indicate that this xenserver is the compute node of my Controller on Ubuntu 12.04 LTS (used devstack) ?

I'd suggest you follow the devstack installation guide at https://wiki.openstack.org/wiki/XenServer/DevStack. There is a handy script there which makes installation of devstack on an existing XenServer or other XenAPI host very straight forward.
It would also be helpful to review http://docs.openstack.org/trunk/openstack-compute/admin/content/introduction-to-xen.html to understand how the host is setup for Nova in XenServer since the nova code lives in a virtual machine to isolate it from the privileged domain 0.

1) Controller on Ubuntu 12.04 LTS (used devstack)
2) Node Compute on Ubuntu 12.04 LTS with KVM hypervisor (used devstack)
And i would like to have a node compute on xenserver. But i don't know how to do it. Can you help me and say me the steps to do it, please ?
