f170548502 util: Add TLS attributes to virStorageSource
Add an optional virTristateBool haveTLS to virStorageSource to
manage whether a storage source will be using TLS.

Sample XML for a VxHS disk:

<disk type='network' device='disk'>
  <driver name='qemu' type='raw' cache='none'/>
  <source protocol='vxhs' name='eb90327c-8302-4725-9e1b-4e85ed4dc251' tls='yes'>
    <host name='192.168.0.1' port='9999'/>
  </source>
  <target dev='vda' bus='virtio'/>
</disk>

Additionally add a tlsFromConfig boolean to control whether the TLS
setting was due to domain configuration or qemu.conf global setting
in order to decide whether to Format the haveTLS setting for either
a live or saved domain configuration file.

Update the qemuxml2xmltest in order to add a test to show the proper
parsing.

Also update the docs to describe the tls attribute.

80740d9c66 Revert "vhost-user: add support reconnect for vhost-user ports"
This reverts commit edaf4ebe95a5995585c8ab7bc5b92887286d4431.

This uses "reconnect" as attribute for <source> element, but we already
have a <reconnect> element for <source> element for chardev devices.

Since this is the same feature for different device it should be
presented in XML the same way.

    <serial>eb90327c-8302-4725-9e1b-4e85ed4dc251</serial>
    <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>

b494e09d05 docs: schema: make disk driver name attribute optional
/domain/devices/disk/driver/@name is not a required or mandatory
attribute according to formatdomain, and indeed it was agreed on
IRC that the attribute is "optional for input, recommended (but
not required) for output". Currently the schema requires the
attribute, causing virt-xml-validate to fail on disk config where
the driver name is not explicitly specified. E.g.

# cat test.xml | grep -A 5 cdrom
    <disk type='file' device='cdrom'>
      <driver type='raw'/>
      <target dev='hdb' bus='ide'/>
      <readonly/>
      <address type='drive' controller='0' bus='0' target='0' unit='1'/>
    </disk>

# virt-xml-validate test.xml
Relax-NG validity error : Extra element devices in interleave
test.xml:21: element devices: Relax-NG validity error : Element domain failed to validate content
test.xml fails to validate

Relaxing the name attribute to be optional fixes the validation

# virt-xml-validate test.xml
test.xml validates

426929aea9 lxc: add possibility to define init uid/gid
Users may want to run the init command of a container as a special

elements. Note that the user can either provide a name or an ID to
specify the user / group to be used.

This commit also fixes a side effect of being able to run the command
as a non-root user: the user needs rights on the tty to allow shell

78fc843c7b bhyve: add vga configuration for video driver
Add support for vgaconf driver configuration. In domain xml it looks like
this:

  <video>
    <driver vgaconf='io|on|off'>
    <model .../>
  </video>

It was added with bhyve gop video in mind to allow users control how the
video device is exposed to the guest, specifically, how VGA I/O is
handled.

One can refer to the bhyve manual page to get more detailed description
of the possible VGA configuration options:

https://www.freebsd.org/cgi/man.cgi?query=bhyve&manpath=FreeBSD+12-current

The relevant part could be found using the 'vgaconf' keyword.

80af11d3dd conf: Introduce @access to <memory/>
Now that NVDIMM has found its way into libvirt, users might want
to fine tune some settings for each module separately. One such
setting is 'share=on|off' for the memory-backend-file object.
This setting - just like its name suggest already - enables
sharing the nvdimm module with other applications. Under the hood
it controls whether qemu mmaps() the file as MAP_PRIVATE or
MAP_SHARED.

Yet again, we have such config knob in domain XML, but it's just
an attribute to numa <cell/>. This does not give fine enough
tuning on per-memdevice basis so we need to have the attribute
for each device too.

b4e8a49f8d Introduce NVDIMM memory model
NVDIMM is new type of memory introduced into QEMU 2.6. The idea
is that we have a Non-Volatile memory module that keeps the data
persistent across domain reboots.

At the domain XML level, we already have some representation of
'dimm' modules. Long story short, NVDIMM will utilize the
existing <memory/> element that lives under <devices/> by adding
a new attribute 'nvdimm' to the existing @model and introduce a
new <path/> element for <source/> while reusing other fields. The
resulting XML would appear as:

    <memory model='nvdimm'>
      <source>
        <path>/tmp/nvdimm</path>
      </source>
      <target>
        <size unit='KiB'>523264</size>
        <node>0</node>
      </target>
      <address type='dimm' slot='0'/>
    </memory>

So far, this is just a XML parser/formatter extension. QEMU
driver implementation is in the next commit.
