[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH 07/19] libxl: add PVH support to domain creation
Remove the device model "none" support from domain creation and
introduce support for PVH.
This requires changing some of the HVM checks to be applied for both
HVM and PVH.
