8fb7c0c506 docs: Remove one example from pci-addresses.rst
The idea behind this document is to show, with actual examples,

5590fe160b docs: Move sections around in pci-addresses.rst
The section about VFIO devices is kept separate from the rest
because it's less about domain XML and guest OS disagreeing on the
PCI address of a device, and more about which of the two PCI
addresses in the domain XML is even relevant to the guest OS.

The section on zPCI addresses, on the other hand, falls squarely
in the "more complex cases" category, so it should live in the
corresponding section.

78f4d5e6f1 conf: new attribute "hotplug" for pci controllers
a <controller type='pci'...> element can now have a "hotplug"
attribute in the <target> subelement. This is intended to control
whether or not the slot(s) of the controller support
hotplugging/unplugging a device:

   <controller type='pci' model='pcie-root-port'>
     <target hotplug='off'/>
   </controller>

The default value of hotplug is "on".

Since support for configuring such an option is hypervisor-dependent
(and will vary among different types of PCI controllers even on a
single hypervisor), no validation is done in this patch - that
validation will be done in the patch that wires support for the
setting into the hypervisor.

f68601dd72 formatdomain.html.in: document emulator/vcpu pin delay
In a guest with only one vcpu, when pinning the emulator in say CPU184
and the vcpu0 in CPU0 of the host, the user might expect that only
CPU0 and CPU184 of the host will be used by the guest.

The reality is that Libvirt takes some time to honor the emulator
and vcpu pinning, taking care of NUMA constraints first. This will
result in other CPUs of the host being potentially used by the
QEMU thread until the emulator/vcpu pinning is done. The user
then might be confused by the output of 'virsh cpu-stats' in this
scenario, showing around 200 microseconds of cycles being spent
in other CPUs.

Let's document this behavior, which is explained in detail in
Libvirt commit v5.0.0-199-gf136b83139, in the cputune section
of formatdomain.html.in.

8e669b382c conf: Add a new xenbus controller option for event channels
Event channels are like PV interrupts and in conjuction with grant frames
form a data transfer mechanism for PV drivers. They are also used for
inter-processor interrupts. Guests with a large number of vcpus and/or
many PV devices many need to increase the maximum default value of 1023.
For this reason the native Xen config format supports the
'max_event_channels' setting. See xl.cfg(5) man page for more details.

Similar to the existing maxGrantFrames option, add a new xenbus controller
option 'maxEventChannels', allowing to adjust the maximum value via libvirt.

0895a0e75d formatdomain.html.in: fix 'sockets' info in topology element
In the 'topology' element it is mentioned, regarding the sockets
value, "They refer to the total number of CPU sockets".

This is not accurate. What we're doing is calculating the number
of sockets per NUMA node, which can be checked in the current
implementation of virHostCPUGetInfoPopulateLinux(). Calculating
the total number of sockets would break the topology sanity
check nodes*sockets*cores*threads=online_cpus.

This documentation fix is important to avoid user confusion when
seeing the output of 'virsh capabilities' and expecting it to be
equal to the output of 'lscpu'. E.g in a Power 9 host this 'lscpu'
output:

Architecture:        ppc64le
Byte Order:          Little Endian
CPU(s):              160
On-line CPU(s) list: 0-159
Thread(s) per core:  4
Core(s) per socket:  20
Socket(s):           2
NUMA node(s):        2
Model:               2.2 (pvr 004e 1202)
Model name:          POWER9, altivec supported

And this XML output from virsh capabilities:

    <cpu>
      <arch>ppc64le</arch>
      <model>POWER9</model>
      <vendor>IBM</vendor>
      <topology sockets='1' dies='1' cores='20' threads='4'/>
      (...)
    </cpu>

Both are correct, as long as we mention in the Libvirt documentation
that 'sockets' in the topology element represents the number of sockets
per NUMA node.

d146105f1e virCommand: Actually acquire pidfile instead of just writing it
Our virCommand module allows us to set a pidfile for commands we
want to spawn. The caller constructs the string of pidfile path
and then uses virCommandSetPidFile() to tell the module to write
the pidfile once the command is ran. This usually works, but has
two flaws:

1) the child process does not hold the pidfile open & locked.
Therefore, the caller (or anybody else) can't use our fancy
virPidFileForceCleanupPath() function to kill the command
afterwards. Also, for everybody else on the system it's
needlessly harder to check if the pid from the pidfile is still
alive or not.

2) if the caller ever makes a mistake and passes the same pidfile
path for two different commands, the start of the second command
will overwrite the pidfile even though the first command might
still be running.

NOTE that this temporarily renders some command spawning
unusable, specifically those code patterns where both
virCommandSetPidFile() is used together with instructing spawned
command to acquire pidfile itself. Fortunately, there is only one
occurrence of such pattern and it is in
qemuProcessStartManagedPRDaemon(). This is fixed in next commit.

08ed673901 conf: Introduce optional 'uuid' element for NVDIMM memory
ppc64 NVDIMM support was implemented in QEMU by commit [1].
The support is similar to what x86 already does, aside from
an extra 'uuid' element.

This patch introduces a new optional 'uuid' element for the
NVDIMM memory model. This element behaves like the 'uuid'
element of the domain definition - if absent, we'll create
a new one, otherwise use the one provided by the XML.
The 'uuid' element is exclusive to pseries guests and are
unavailable for other architectures.

Next patch will use this new element to add NVDIMM support
for ppc64.
