[Qemu-devel] [PATCH] Add "boot_linux" acceptance test

[Cleber Rosa]

This acceptance test, validates that a full blown Linux guest can
successfully boot in QEMU.  In this specific case, the guest
chosen is Fedora version 28.  By passing parameters, the same
test can attempt to boot different distros, arches, etc.

The method for checking the successfull boot is based on "cloudinit"
and its "phone home" feature.  The guest is given an ISO image
with the location of the phone home server, and the information to
post (the instance ID).  Upon receiving the correct information,
from the guest, the test is considered to have PASSed.

This test is currently limited to user mode networking only, and
instructs the guest to connect to the "router" address that is hard
coded in QEMU.

This test requires features present in Avocado version 64.0, and when
running under Python 3, requires a fix to the avocado.utils.vmimage
library (to be included in version 65.0).  To create the cloudinit ISO
image that will be used to configure the guest, the pycdlib library is
also required.  The idea for a effortless execution of this test, is
to set those requirements, that is:

   avocado-framework==65.0
   pycdlib==1.6.0

In the "tests/venv-requirements.txt" file introduced in another patch
series.
