Hi,<div><br></div><div>Thanks a lot for your answer.</div><div>Here is the link of the tutorial that I used to install OpenStack: <a href="http://docs.openstack.org/essex/openstack-compute/install/apt/openstack-install-guide-essex.pdf">http://docs.openstack.org/essex/openstack-compute/install/apt/openstack-install-guide-essex.pdf</a></div>
<div>Page 41 shows an overview of the architecture of OpenStack with Xen.</div><div>Actually, I am trying to use libvirt to connect to the hypervisor. I modified a little the code of openstack to make the connection to the hypervisor from a para virtualized domU possible (just modified the url to let make a remote connection).</div>
