Explicitly select PV vs HVM mode
Registered by

Currently for Xen, there is a complex process of deciding if an instance should be run in PV or HVM mode. In practice, setting the os_type to 'windows' is commonly used, even if the OS being run is not Windows.

Whiteboard
I propose adding a vm_mode property to images that selects PV or HVM mode. As a transition, if the property does not exist, then the existing behavior is used to determine what mode should be used.
