[Xen-devel] How to use PV drivers with fully virtualized HVM on x86?

[Jintack Lim <jintack@xxxxxxxxxxxxxxx>]

Hi,

I'm interested running HVM DomU only with PV drivers (network and
disk). Enabling CONFIG_XEN_NETDEV_FRONTEND and stuff didn't make DomU
see the PV devices until I enabled CONFIG_XEN_PVHVM.

But by looking at the virtualization spectrum[1], it seems possible to
do "HVM with PV drivers", but I couldn't find any guide (i.e.
kernel/xen configuration) to do that. Could anyone shed some light on
this?

I'm currently using Linux kernel 4.15, and Xen 4.10.1.

Thanks,
Jintack
