Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/allow-windows-builds-with-xentools6-1-and-6-2.

Description:

Windows builds with pre-installed xentools version >= 6.1 require the property 'device_id' to be set on the xen vm record for the VM to build successfully. Also, the device_id needs to be set only if the hypervisor version is greater than or equal to 6.1
For eg, the device_id requires to be set to "0002" in case of Windows with xen tools version >= 6.1

for more information.

Requires:
In Glance, the property 'xenapi_device_id' has to be set on the image_metadata for such images which require a device_id to be built.

Approach taken:
In Nova, the property 'xenapi_device_id' on the image_metadata is copied over to the xen vm record before vm create is invoked.
