Open Stack

Hi Xi,

Do you have some logs available? The log messages would help a lot in
findinf the issue.

Look at how devstack works, that's always a good starting point.

https://github.com/openstack-dev/devstack/tree/master/tools/xen

For me, it seems, that xenapi_connection_url does not contain the http
prefix. That could be an issue - again, logs would help.

I would suggest to look at the devstack setup for a reference.

Also, you have to be aware, that the XenSever installation will have a
slightly different architecture, compared to KVM:

http://docs.openstack.org/havana/config-reference/content/introduction-to-xen.html

Let me know if you need more help.

Cheers,
Mate
