Open Stack

Hi,

Thanks a lot for your answer.
Here is the link of the tutorial that I used to install OpenStack:
http://docs.openstack.org/essex/openstack-compute/install/apt/openstack-install-guide-essex.pdf
Page 41 shows an overview of the architecture of OpenStack with Xen.
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).

Regards,
Afef
