Open Stack

There is a very big error in screen-n-cpu – claiming that the compute and controller machines are not running compatible versions.

Note that the XVA you have used is not the Havana XVA, yet you are trying to use the Havana controller from Ubuntu.  As a minimum you need to use compatible versions between your controller and compute nodes.  That may be as simple as using the XVA and plugins from:

http://downloads.vmd.citrix.com/OpenStack/devstack-havana.xva
http://downloads.vmd.citrix.com/OpenStack/novaplugins-havana.iso

Hi, Bob:

Seems the last email did not go through due to large attachment. I compressed the log and is re-sending them now.

Thanks for your reply and help!

I am using a fresh XenServer 6.2 with SP1, and with the devstack-2013_12_19.xva and novaplugins-2013_12_19.iso found on the website.

I have another machine works as the controller, where I followed the guide to install OpenStack Havana on Ubuntu Server 12.04.

I followed the script and changed my setting in the localrc, it is now:

After that, I ran the unstack.sh, and then run.sh under /opt/stack/.

However, I still cannot see the compute node from my controller node.

I am also attaching the log files from stack.

Can you help me with this?

Thanks very much!

Hi Sisu,

You can easily convert a VM running all services in devstack to one running just the services needed for compute (nova-compute and nova-network in the case of the stock method for setting up devstack with XenServer).

There is a script at https://github.com/citrix-openstack/qa/blob/master/connect-devstack-local.sh - download this to the devstack instance you want to just run compute services, and run it passing the IP address of the devstack that hosts the rest of the services.
If you’ve got a split of where the other services are, check out the details in the script – it’s actually quite simple to change hosts in the localrcs.

Note that this will not convert an “AllInOne” devstack to a standalone compute node – it will still be using devstack, but just configuring it to run only the compute services.

Thanks,

Bob

Subject: [Openstack] Turn a XenServer AllInOne Node into a Compute Node?

Hi,

I was having trouble configuring a XenServer Node into an computer Node, the tutorial/devstack are all for using XenServer as a single allinone node.

For example, I found this really nice VM image from citrix at:
http://downloads.vmd.citrix.com/OpenStack/
which includes pre-build XenServer patch and images. I can just import them into XenServer and everything works.

Is there any easy way to turn this AllInOne XenServer Node into just a compute node? Of course I have another machine works as the controller node, installed following the OpenStack installation guide.

Thanks very much!

Sisu
