Hi Alex, 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: ENABLED_SERVICES="n-cpu,n-net,n-api,g-api,-mysql" DATABASE_TYPE=mysql MYSQL_HOST=<controller IP> RABBIT_HOST=<controller IP> KEYSTONE_AUTH_HOST=<controller IP> GLANCE_HOSTPORT=<controller IP>:9292 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.

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) ? Alex 2013/5/14 Bob Ball <bob.b...@citrix.com<mailto:bob.b...@citrix.com>> Hi Alexandre, Interesting question! 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.

I have 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 ? -- regards, Alexandre -- Cordialement, Alexandre DE CARVALHO
