[PATCH 1/2] tests/acceptance: Add PVH boot test

[Wainer dos Santos Moschetta]

QEMU 4.0 onward is able to boot an uncompressed kernel
image by using the x86/HVM direct boot ABI. It needs
Linux >= 4.21 built with CONFIG_PVH=y.

This introduces an acceptance test which checks an
uncompressed Linux kernel image boots properly.
