"""Constants and helper APIs for dealing with virtualization types

The constants provide the standard names for all known guest
|
|
virtualization types. This is not to be confused with the Nova
|
|
hypervisor driver types, since one driver may support multiple
|
|
virtualization types and one virtualization type (eg 'xen') may
|
|
be supported by multiple drivers ('XenAPI' or 'Libvirt-Xen').
