I seriously question this being a good approach, since I can't see why
what is appropriate here for PV shouldn't also be appropriate for PVH
or HVMlite. Did you indeed try with at least one of the device kinds
that get marked r/o (AMD IOMMU, PCI serial card used by hypervisor,
EHCI device with debug port used by hypervisor, "vga=keep" used)
at present?
