Hi all,<div><br></div><div>I used devstack to install openstack on an ubuntu 12.04 with xcp.</div><div>I followed this link: <a href="https://github.com/openstack-dev/devstack/blob/master/tools/xen/README.md">https://github.com/openstack-dev/devstack/blob/master/tools/xen/README.md</a></div>
<div>The script installed almost everything. The dashboard is working and shows that all services are running.</div><div>However, launching "nova-manage service list" shows that nova-compute is not working.</div>
<div>I also was unable to launch an instance from the dashboard and command line.</div><div>Here are errors shown by nova-compute.</div><div>Is there any way to solve this problem?</div><div><br></div><div>-------------------------------------------------------</div>
