No problem, sorry you hit so many problems. This is very dependent on how you have configured your guest network and Floating IP addresses.
I suspect if you have a machine on the same network and subnet as your VM, it will just work. If you could give the ifconfig details from your DomU, Dom0 and VM launched via dashboard, I should be able to help more.

Thanks a lot for your help. Now, I could launch an instance from the dashboard. It has an ip address. Unfortunately, I can ping and ssh this instance only from the privileged DomU. How can I let this instance accessible from all machines of my network? Thank you, Afef 2012/10/2 John Garbutt <john.garb...@citrix.com<mailto:john.garb...@citrix.com>> OK, so XCP-XAPI install is not that well documented yet. There is at least one manual step to make the XenAPI plugins work. What you need to run, on your Dom0 is this: sudo mkdir -p /usr/etc I think it is simply not present because it is Ubuntu and not CentOS 5.x that you get with XenServer and the XCP ISO.

I followed this link: https://github.com/openstack-dev/devstack/blob/master/tools/xen/README.md The script installed almost everything. The dashboard is working and shows that all services are running. However, launching "nova-manage service list" shows that nova-compute is not working. I also was unable to launch an instance from the dashboard and command line. Here are errors shown by nova-compute. Is there any way to solve this problem? ------------------------------------------------------- 2012-10-02 09:34:10 DEBUG nova.virt.xenapi.driver [-] Got exception: ['XENAPI_PLUGIN_FAILURE', 'host_data', 'IOError', "[Errno 2] No such file or directory: '/usr/etc/xenhost.conf'"] from (pid=4770) _unwrap_plugin_exceptions /opt/stack/nova/nova/virt/xenapi/driver.py:728 2012-10-02 09:34:10 ERROR nova.virt.xenapi.host [-] The call to host_data returned an error: ['XENAPI_PLUGIN_FAILURE', 'host_data', 'IOError', "[Errno 2] No such file or directory: '/usr/etc/xenhost.conf'"].
