For certain applications it is desirable to rapidly boot a KVM virtual

uncompressed Linux kernel binary without the need to run firmware.

There already exists an ABI to allow this for Xen PVH guests and the ABI
is supported by Linux and FreeBSD:

This patch series would enable Qemu to use that same entry point for
booting KVM guests.
Thanks! I should be able to post a Tested-by next Monday. Boris, are
you going to pick it up for 4.21?

Hi Paolo,

Are you still planning on running some testing of your own for these patches? Should Boris wait to hear from you before moving forward?

Thanks,
