d53e75aad0 conf: Introduce 'absolute' clock offset
The 'absolute' clock offset type has a 'start' attribute which is an
unix epoch timestamp to which the hardware clock is always set at start
of the VM.

This is useful if some VM needs to be kept set to an arbitrary time for
e.g. testing or working around broken software.

This patch allows us to track the used fdset id so that we can avoid the

05b09f039e conf: add qemu-vdagent channel
Add the ability to configure a qemu-vdagent in guest domains. This
device is similar to the spice vdagent channel except that qemu handles
the spice-vdagent protocol messages itself rather than routing them over
a spice protocol channel.

The qemu-vdagent device has two notable configuration options which
determine whether qemu will handle particular vdagent features:
'clipboard' and 'mouse'.

The 'clipboard' option allows qemu to synchronize its internal clipboard
manager with the guest clipboard, which enables client<->guest clipboard
synchronization for non-spice guests such as vnc.

The 'mouse' option allows absolute mouse positioning to be sent over the
vdagent channel rather than using a usb or virtio tablet device.

Sample configuration:
  <channel type='qemu-vdagent'>
    <target type='virtio' name='com.redhat.spice.0'/>
    <source>
      <clipboard copypaste='yes'/>
      <mouse mode='client'/>
    </source>
  </channel>

bb6cedd208 cpu_x86: Ignore enabled features for input models in x86DecodeUseCandidate
While we don't want to aim for the shortest list of disabled features in
the baseline result (it would select a very old model), we want to do so
while looking at any of the input models for which we're trying to
compute a baseline CPU model. Given a set of input models, we always
want to take the least capable one of them (i.e., the one with shortest
list of disabled features) or a better model which is not one of the
input models.

So when considering an input model, we just check whether its list of
disabled features is shorter than the currently best one. When looking
at other models we check both enabled and disabled features while
penalizing disabled features as implemented by the previous patch.

48341b025a cpu_x86: Penalize disabled features when computing CPU model
For finding the best matching CPU model for a given set of features
while we don't know the CPU signature (i.e., when computing a baseline
CPU model) we've been using a "shortest list of features" heuristics.
This works well if new CPU models are supersets of older models, but
that's not always the case. As a result it may actually select a new CPU
model as a baseline while removing some features from it to make it
compatible with older models. This is in general worse than using an old
CPU model with a bunch of added features as a guest OS or apps may crash
when using features that were disabled.

On the other hand we don't want to end up with a very old model which
would guarantee no disabled features as it could stop a guest OS or apps
from using some features provided by the CPU because they would not
expect them on such an old CPU.

This patch changes the heuristics to something in between. Enabled and
disabled features are counted separately so that a CPU model requiring
some features to be disabled looks worse than a model with fewer
disabled features even if its complete list of features is longer. The
penalty given for each additional disabled feature gets bigger to make
longer list of disabled features look even worse.

from the binary itself (which also links with

As of ad81aa8ad0 the qemuhotplugmock.c calls
testQemuPrepareHostBackendChardevOne() which is implemented in

particularly) unhappy because the resulting mock library has
unresolved symbol.

The fix is simple, link mock library with test_utils_qemu_lib and
also with test_utils_lib since testutils.c calls some functions
from testutils.c.

Since these two libraries are declared only after mock_libs[], I
had to move the line that declares qemuhotplugmock after those
two.

On macOS when BROKEN_POLL is set in GLib, our tests will periodically
trigger a warning:

  (process:50880): GLib-WARNING **: 02:54:15.272: poll(2) failed due to: Bad file descriptor.

Our code is inherantly racy, calling g_source_destroy which
removes the FD from the event thread poll asynchronously but
we close the FD immediately after g_source_destroy returns.

With poll() this results in POLLNVAL which we're ignoring, but
with select() it generates the BADF error on macOS.

We need to ignore the warnings on macOS to avoid abort()ing
our test programs.
