ea4769a1b5 news: Make changes understandable for users
When reading release notes, patch summary is not always the best
description of what users can expect in new version.  I propose
changing it slightly so that it describes what exactly happens and
when.

However, we do not have to add every single code change to the news
file, that would be ridiculous and unreadable for users.  If the patch
subject needs changes like this one, I'm rather tempted to say that
such changes should not be in the news file at all.  So that would be
the other way how to fix this.

ca4515d263 storage: Better describe logical pool creation/definition parameters
https://bugzilla.redhat.com/show_bug.cgi?id=1398087

Clean up the virsh man page description for --pool-create-as in order
to better describe how the various arguments are used when creating
(or defining) a logical pool.

Also modify the storage pool XML parsing algorithm to check for the
mismatched "name" and "source-name".

4572843d4a conf: Set defaultFormat if no storage source XML present
While parsing if the storage source is not present, then a defaultFormat
was not set. This could lead to oddities such as seeing "unknown" format
in output for the "logical" pool even though the only format the pool could
support would be "lvm2".

This does "put a label" on other pool defaults as follows:

   File System: FS_AUTO
   Network File System: NETFS_AUTO
   Disk: UNKNOWN

Each of which is the "0" value for their respective pools and thus
would be no "real" change.

7373c4e48f qemu: Add support for setting TSC frequency
QEMU allows for TSC frequency to be explicitly set to enable migration
with invtsc (migration fails if the destination QEMU cannot set the
exact same frequency used when starting the domain on the source host).

Libvirt already supports setting the TSC frequency in the XML using

    <clock>
      <timer name='tsc' frequency='1234567890'/>
    </clock>

which will be transformed into

    -cpu Model,tsc-frequency=1234567890

QEMU command line.

6760cc4bfd logical: Need to overwrite/clear more than just first 512 bytes
https://bugzilla.redhat.com/show_bug.cgi?id=1430679

As it turns out some file headers (e.g. ext4) may be larger/longer than
the 512 bytes of zeros being written prior to a pvcreate, so let's write
out 2048 bytes similar to how the pvcreate sources would peek at the first
4 sectors of the device.

Make sure there is at enough bytes on the device to clear before doing
doing the clear - just to be sure.

5c8d622f5d network: better validation of devices in hostdev network pool

* devices must be listed by PCI address, not by netdev name

* listing a device by PCI address is valid only for hostdev networks, not
  for other types of network (e.g. macvtap passthrough).

* each device in a hostdev pool must be an SR-IOV VF

84cc51ea74 cputest: Add tests for virCPUUpdateLive API
The test takes

  x86-cpuid-Something-guest.xml CPU (the CPU libvirt would use for
    host-model on a CPU described by x86_64-cpuid-Something.xml without
    talking to QEMU about what it supports on the host)

and updates it according to CPUID data from QEMU:

  x86_64-cpuid-Something-enabled.xml (reported as "feature-words"
    property of the CPU device)

and

  x86_64-cpuid-Something-disabled.xml (reported as "filtered-features"
    property of the CPU device).

The result is compared to

  x86_64-cpuid-Something-json.xml (the CPU libvirt would use as
    host-model based on the reply from query-cpu-model-expansion).

The comparison is a bit tricky because the *-json.xml CPU contains fewer
disabled features. Only the features which are included in the base CPU
model, but listed as disabled in *.json will be disabled in *-json.xml.
The CPU computed by virCPUUpdateLive from the test data will list all
features present in the host's CPUID data and not enabled in *.json as
disabled. The cpuTestUpdateLiveCompare function checks that the computed
and expected sets of enabled features match.

2aeef0f6be cputest: Add "diff" command to cpu-cpuid.py
The new command can be used to generate test data for virCPUUpdateLive.

When "cpu-cpuid.py diff x86-cpuid-Something.json" is run, it reads raw
CPUID data stored in x86-cpuid-Something.xml and CPUID data from QEMU
stored in x86-cpuid-Something.json to produce two more CPUID files:
x86-cpuid-Something-enabled.xml and x86-cpuid-Something-disabled.xml.

- x86-cpuid-Something-enabled.xml will contain CPUID bits present in
    x86-cpuid-Something.json (i.e., enabled by QEMU for the "host" CPU)

- x86-cpuid-Something-disabled.xml will contain all CPUID bits from
    x86-cpuid-Something.xml which are not present in
    x86-cpuid-Something.json (i.e., CPUID bits which the host CPU
    supports, but QEMU does not enable them for the "host" CPU)
