[PATCH 9/9] tests/avocado: Add FreeBSD distro boot tests for ppc

[Nicholas Piggin]

FreeBSD project provides qcow2 images that work well for testing QEMU.
Add pseries tests for HPT and Radix, KVM and TCG. This uses a short
term VM image, because FreeBSD has not set up long term builds for
ppc64 at present.

Other architectures could be added so this does not get a ppc_ prefix
but is instead named similarly to boot_linux.

Unfortunately the latest stable (14.0) x86-64 VM image does not seem to
output to console by default and I've not been able to find a reliable
way to edit the filesystem to change the boot loader options, or use
console input in the test case to change it on the fly.

Thanks,
Nick
