A long time ago we imported the keymaps.csv file from GTK-VNC so we
can do conversions between keycode sets. Meanwhile lots of bug fixes
have gone into this CSV file and libvirt hasn't kept in sync. The
keymaps.csv file and associated generator script has been pulled out
of GTK-VNC into a dedicated GIT repo for use as a submodule. This
allows GTK-VNC, SPICE-GTK, QEMU and libvirt to share the same master
database and tools and pushing updates merely requires a submodule
commit update as with gnulib.

The test suite is updated to cover some extra boundary conditions.

This patch makes use of the virNetDevSetCoalesce() function to make
appropriate settings effective for devices that support them.

We are currently parsing only rx/frames/max because that's the only
value that makes sense for us.  The tun device just added support for
this one and the others are only supported by hardware devices which
we don't need to worry about as the only way we'd pass those to the
domain is using <hostdev/> or <interface type='hostdev'/>.  And in
those cases the guest can modify the settings itself.

We already know from QEMU which CPU features will block migration. Let's
use this information to make a migratable copy of the host CPU model and
use it for updating guest CPU specification. This will allow us to drop
feature filtering from virCPUUpdate where it was just a hack.

When running tests in a restricted container (as opposed to a full
OS install), we can't assume ebtables/iptbles/ip6tables are going
to be installed. We must check this and mark the tests as skipped.

Commit 4f4c3b13 added code to remember errors during freeing

parsing in virsh-optparse. Adjust the expected output.

This removes the hacky extern global variable and modifies the

Our test data used a lot of different qemu binary paths and some
of them were based on downstream systems.

Note that there is one file where I had to add "accel=kvm" because
the qemuargv2xml code parses "/usr/bin/kvm" as virt type="kvm".

The virt type for QEMU can be modified by -machine attribute "accel"

Introduce STRICT_FRAME_LIMIT_CFLAGS that will be used for
production code and RELAXED_FRAME_LIMIT_CFLAGS for tests.

Raising the limit for tests allows building them with clang
with optimizations disabled.

This header file has been created so that we can expose
internal functions to the test suite without making them
public: those in qemu_capabilities.h bearing the comment

  /* Only for use by test suite */

are obvious candidates for being moved over.

docs/schemas directory is meant for schemas which are installed on the

We use the "vir" prefix pretty consistently in our
APIs, both external and internal, which made these
macros stood out.

For native gluster pools the <dir> field denotes a directory inside the
pool. For the actual pool name the <name> field has to be used.

Use the relative lookup specifier rather than the global one. Otherwise
only the first name would be looked up. Add a test case to cover the
scenario.

Add a test program called virstorageutiltest and test the gluster pool

Like all devices, add the 'id' option for mdevs as well. Patch also

Make sure every combination of ACPI and UEFI works, or fails to
work, as expected.

Depending on the architecture, requirements for ACPI and UEFI can
be different; more specifically, while on x86 UEFI requires ACPI,
on aarch64 it's the other way around.

Enforce these requirements when validating the domain, and make
the error message more accurate by mentioning that they're not
necessarily applicable to all architectures.

Several aarch64 test cases had to be tweaked because they would
have failed the validation step otherwise.

So far, libvirt has assumed that only x86 supports ACPI,
but that's inaccurate since aarch64 supports it too.

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1429509

Now that the NO_ACPI and NO_HPET capabilities are set
automatically by virQEMUCapsInitQMPBasicArch() if
appropriate for the architecture, they shouldn't be
used manually to avoid masking bugs.

The capabilities used in test cases should match those used
during normal operation for the tests to make any sense.

This results in the generated command line for a few test
cases (most notably non-x86 test cases that were wrongly
assuming they could use -no-acpi) changing.

Since this file gets changed (and broken) rather often, introduce a
schema file so that the test suite can validate it.
