Subject: [kvm-unit-tests PATCH RESEND v3 1/2] x86: Build ISO images from x86/*.elf
Date: Tue,  7 Dec 2021 17:44:31 +0800	[thread overview]
Message-ID: <20211207094432.189576-2-yi.sun@intel.com> (raw)
In-Reply-To: <20211207094432.189576-1-yi.sun@intel.com>

Make use of tool grub-mkresure to wrap x86/*.elf in ISO images.
VMM could load test cases just like a CD-ROM, which could
extend usage of those cases.

Refine Makefile to clean *.iso when running 'make clean'.
