From the OpenStack Documentation:
"The OpenStack Open Source Cloud Mission: to produce the ubiquitous Open Source Cloud Computing platform that will meet the needs of public and private clouds regardless of size, by being simple to implement and massively scalable."
USING XAPI
The OpenStack documentation reads:
"The recommended way to use Xen with OpenStack is through the XenAPI driver. To enable the XenAPI driver, add the following configuration options /etc/nova/nova.conf and restart the nova-compute service:"
compute_driver = xenapi.XenAPIDriver xenapi_connection_url = http://your_xenapi_management_ip_address xenapi_connection_username = root xenapi_connection_password = your_password
"These connection details are used by the OpenStack Compute service to contact your hypervisor and are the same details you use to connect XenCenter, the XenServer management console, to your XenServer or XCP box."
The OpenStack documentation does not reflect the current reality. While XAPI is the clear mechanism for supporting XenServer at this time, most existing Xen Project integration into OpenStack is done through libvirt below.
USING LIBVIRT
The OpenStack documentation reads:
"It is possible to manage Xen using libvirt, though this is not well-tested or supported. To experiment using Xen through libvirt add the following configuration options /etc/nova/nova.conf:"
compute_driver = libvirt.LibvirtDriver [libvirt] virt_type = xen
Beyond what the documentation says, however, there are now high-quality instances of libvirt being used to control the Xen Project hypervisor under OpenStack. SUSE and Oracle are both using that technique in commercial OpenStack implementations.
