76e1720c4f rpc: avoid duplicating config in virtlockd/virtlogd augeas tests
Most of the augeas test files use ::CONFIG:: to pull in the master
config file for testing. This ensures that entries added to the config
file are actually tested by augeas.

This identified the missing admin_max_clients example in the virtlogd
config file, which in turn prompted a change in description of the
max_clients parameter, since these daemons don't have separate
readonly & readwrite sockets.

65824a7e45 rpc: remove remains of obsolete log_buffer_size config parameter
The global log buffer feature was deleted in:

  commit c0c8c1d7bb
  Author: Daniel P. Berrange <berrange@redhat.com>
  Date:   Mon Mar 3 14:54:33 2014 +0000

    Remove global log buffer feature entirely

    A earlier commit changed the global log buffer so that it only
    records messages that are explicitly requested via the log
    filters setting. This removes the performance burden, and
    improves the signal/noise ratio for messages in the global
    buffer. At the same time though, it is somewhat pointless, since
    all the recorded log messages are already going to be sent to an
    explicit log output like syslog, stderr or the journal. The
    global log buffer is thus just duplicating this data on stderr
    upon crash.

    The log_buffer_size config parameter is left in the augeas
    lens to prevent breakage for users on upgrade. It is however
    completely ignored hereafter.

    Signed-off-by: Daniel P. Berrange <berrange@redhat.com>

This was in the 1.2.3 release, and 4 years is sufficient time for a
graceful upgrade path for augeas, so all remaining traces are now
removed.

virt-aa-helper: test: check for expected profile content
So far the virt-aa-helper tests only checked the return code and thereby
catched aborts like issues failing to parse the XML. But there is one
category of virt-aa-helper issues so far untested - not generating the
expected rule.

This adds a basic grep based checks after each test to match against the
rule that is expected to be added by the test.

virt-aa-helper: generate rules for nvdimm memory
nvdimm memory is backed by a path on the host. This currently works only via
hotplug where the AppArmor label is created via the domain label callbacks.

This adds the virt-aa-helper support for nvdimm memory devices to generate
rules for the needed paths from the initial guest definition as well.

Example in domain xml:
  <memory model='nvdimm'>
    <source>
      <path>/tmp/nvdimm-base</path>
    </source>
    <target>
     <size unit='KiB'>524288</size>
     <node>0</node>
    </target>
  </memory>
Works to start now and creates:
  "/tmp/nvdimm-base" rw,

security, apparmor: add (Set|Restore)InputLabel
d8116b5a "security: Introduce functions for input device hot(un)plug"
implemented the code (Set|Restore)InputLabel for several security modules,
this patch adds an AppArmor implementation for it as well.

That fixes hot-plugging event input devices by generating a rule for the
path that needs to be accessed.

Example hot adding:
  <input type='passthrough' bus='virtio'>
     <source evdev='/dev/input/event0' />
  </input>
Creates now:

83edaf4435 libxl: don't hardcode scheduler weight
Long ago in commit dfa1e1dd53 the scheduler weight was accidentally
hardcoded to 1000. Weight is a setting with no unit since it is
relative to the weight of other domains. If no weight is specified,
libxl defaults to 256.

Instead of hardcoding the weight to 1000, honor any <shares> specified
in <cputune>. libvirt's notion of shares is synonomous to libxl's
scheduler weight setting. If shares is unspecified, defer default
weight setting to libxl.

Removing the hardcoded weight required some test fixup. While at it,
add an explicit test for <shares> conversion to scheduler weight.

7495b1a779 rpm: fix incorrect expansion of macros with line continuations for args
Macros in RPMs are expanded before line continuations, so when we write

What happens is that it expands to

        # Package removal, not upgrade
        systemctl --no-reload disable --now foo \ > /dev/null 2>&1 || :
