Support Linux guests running as HVM mode on XenServer
Currently all HVM guests get the following flag added:
platform:
But this confuses some linux kernels, so linux machines should really get:
platform:
This will be controlled using the existing os_type glance flags.
The viridian flag is used by Xen to provide hyper-v style optimisations to Windows guests. However, if you try these with some linux kernels, strange things can happen. in XenServer, this is all handled with the built-in templates, there is little documentation on the flag its-self.
Some details can be found here:

The issue with Linux boxes can be found here:

Please note, that technically, it the linux guests will still be able to detect the presence of Xen and negotiate the use of PV drivers, despite running inside an HVM container. This is also not quite the same as the PVH mode of operation Xen is currently working on.
