1e48931c0c tests/vm: Allow to set qemu-img path
By default VM build test use qemu-img from system's PATH to
create the image disk. Due the lack of qemu-img on the system
or the desire to simply use a version built with QEMU, it would
be nice to allow one to set its path. So this patch makes that
possible by reading the path to qemu-img from QEMU_IMG if set,
otherwise it fallback to default behavior.

ba21bde930 Acceptance tests: use avocado tags for machine type
The same way the arch tag is being used as a fallback for the arch

This is now possible because, since Avocado 72.0, it's possible to use
tags with names that match the machine types on QEMU.

b910545fbf tests/acceptance: look for target architecture in test tags first
A test can, optionally, be tagged for one or many architectures.  If a
test has been tagged for a single architecture, there's a high chance
that the test won't run on other architectures.  This changes the
default order of choosing a default target architecture to use based
on the 'arch' tag value first.

The precedence order is for choosing a QEMU binary to use for a test
is now:

 * qemu_bin parameter
 * arch parameter
 * arch tag value (for example, x86_64 if "🥑 tags=arch:x86_64
   is used)

This means that if one runs:

 $ avocado run -p qemu_bin=/usr/bin/qemu-system-x86_64 test.py

No arch parameter or tag will influence the selection of the QEMU
target binary.  If one runs:

 $ avocado run -p arch=ppc64 test.py

The target binary selection mechanism will attempt to find a binary
such as "ppc64-softmmu/qemu-system-ppc64".  And finally, if one runs
a test that is tagged (in its docstring) with "arch:aarch64":

 $ avocado run aarch64.py

The target binary selection mechanism will attempt to find a binary
such as "aarch64-softmmu/qemu-system-aarch64".

At this time, no provision is made to cancel the execution of tests if
the arch parameter given (manually) does not match the test "arch"
tag, but it may be a useful default behavior to be added in the
future.

2c44d68f2b tests/acceptance: introduce arch parameter and attribute
It's useful to define the architecture that should be used in
situations such as:
 * the intended target of the QEMU binary to be used on tests
 * the architecture of code to be run within the QEMU binary, such
   as a kernel image or a full blown guest OS image

This commit introduces both a test parameter and a test instance
attribute, that will contain such a value.

Now, when the "arch" test parameter is given, it will influence the
selection of the default QEMU binary, if one is not given explicitly
by means of the "qemu_img" parameter.

b7287d4283 tests.acceptance: adds multi vm capability for acceptance tests
This change adds the possibility to write acceptance tests with multi
virtual machine support. It's done keeping the virtual machines objects
stored in a test attribute (dictionary). This dictionary shouldn't be
accessed directly but through the new method added `get_vm`. This new
method accept a list of args (that will be added as virtual machine
arguments) and an optional name argument. The name is the key that
identify a single virtual machine along the test machines available. If
a name without a machine is informed a new machine will be instantiated.

The current usage of vm in tests will not be broken by this change since
it keeps a property called vm in the base test class. This property only
calls the new method `get_vm` with default parameters (no args and
'default' as machine name).

9531d26c10 Acceptance tests: drop usage of "🥑 enable"
The Avocado test runner attemps to find its INSTRUMENTED (that is,
Python based tests) in a manner that is as safe as possible to the
user.  Different from plain Python unittest, it won't load or
execute test code on an operation such as:

 $ avocado list tests/acceptance/

Before version 68.0, the logic implemented to identify INSTRUMENTED
tests would require either the "🥑 enable" or "🥑
recursive" statement as a flag for tests that would not inherit
directly from "avocado.Test".  This is not necessary anymore,
and because of that the boiler plate statements can now be removed.

29c33cc107 docs/devel/testing: Add -a option to usermod command on docker setup
The option -G of usermod command will remove user from other groups
not listed, i.e.: $USER will belong only to group 'docker' after
following the documentation as is.

From usermod(8) manual page:

    If the user is currently a member of a group which is not listed,
    the user will be removed from the group. This behaviour can be
    changed via the -a option, which appends the user to the current
    supplementary group list.

This patch improves the situation by adding the -a option to the
usermod command, which will just append user to the supplementary
group list.

a56931eef3 Acceptance tests: add make rule for running them
The acceptance (aka functional, aka Avocado-based) tests are
Python files located in "tests/acceptance" that need to be run

Let's provide a convenient way for QEMU developers to run them,

Also, while the Avocado test runner will take care of creating a
location to save test results to, it was understood that it's better
if the results are kept within the build tree.

let's add a document. For example, Patchew reports build errors on
patches that should be relatively easy to reproduce with a few steps, and
it is much nicer if there is such a documentation that it can refer to.

This focuses on how to run existing tests and how to write new test
cases, without going into the frameworks themselves.

The VM based testing section is moved from tests/vm/README which now
is a single line pointing to the new doc.
