Experimental support for running nova in dom0 with XenAPI

Registered by Bob Ball on 2013-08-15

Xenserver-core (http://xenserver.org/blog/entry/tech-preview-of-xenserver-libvirt-ceph.html) can be installed on an existing CentOS 6.4 base system, and therefore the restrictions about running in dom0 are more relaxed (e.g. python2.6 is installed!).

Nova runs in a domU against xenserver-core without any changes, but this blueprint fixes the issues encountered when running nova in dom0. It is fully restricted to the XenAPI driver with no changes needed in stock nova code.

This initial support is limited to being able to boot VMs from local disk using VHDs, and may not include features such as boot from volume, use of security groups, VLANS, etc. Support for further features will be coming in later blueprints and bugs.
