[kvm-unit-tests PATCH RESEND v3 0/2] Wrap EFL binaries into ISO images

[Yi Sun <yi.sun@intel.com>]

This patch set make use of tool 'grub-mkrescue' to wrap ELF binaries into bootable ISO images.

Cases in kvm-unit-tests can be run with QEMU. But the problem is that some newer VMMs such as Crosvm/Cloud-hyperviosr does NOT support multiboot protocol with which QEMU loads and executes those testing binaries correctly. This patch set can wrap each kvm-unit-tests EFL binaries into a bootable ISO image aiming to adapt it to more usage scenarios. As we know, all PC BIOSes and vBIOSes know how to boot from a ISO from CD-ROM drive, hence it can extend the KVM-unit-tests a lot.

The patch set provides two approaches to create ISO. One is via "make iso". It wrap each ELF in foler x86 into a ISO without any parameters passed to the test cases.  The other is via script create_iso.sh. The script wraps the ELF according to the configure file unittests.cfg which descripes various parameters for each testing.

Patch History:
V1: Initial version.
V2: Add the second parament to the script create_iso.sh, that could pass environment variables into test cases via the file.
V3: Add some failure handle.
