Starting from qemu 2.11, the `-device vmcoreinfo` will create a fw_cfg
entry for a guest to store dump details, necessary to process kernel
dump with KASLR enabled and providing additional kernel details.
In essence, it is similar to -fw_cfg name=etc/vmcoreinfo,file=X but in
this case it is not backed by a file, but collected by QEMU itself.
Since the device is a singleton and shouldn't use additional hardware
resources, it is presented as a <feature> element in the libvirt
domain XML.
The device is arm/x86 only for now (targets that support fw_cfg+dma).

While we have collective knowledge about the support status of various
parts of libvirt, this has never been formally documented, leaving our
users to guess.
Note, this document makes one change to our previous policy. It explicitly
declares the RPC protocol of libvirtd as being a supported interface. THis
accepts the reality that we can a) never change it without breaking compat
with old libvirt.so, b) there are both rust + go impls that are written
against the RPC protocol already.

Add support for describing NUMA distances in a domain's <numa> <cell>
XML description.
Below is an example of a 4 node setup:
<cpu>
<numa>
<cell id='0' cpus='0-3' memory='2097152' unit='KiB'>
<distances>
<sibling id='0' value='10'/>
<sibling id='1' value='21'/>
<sibling id='2' value='31'/>
<sibling id='3' value='21'/>
</distances>
</cell>
<cell id='1' cpus='4-7' memory='2097152' unit='KiB'>
<distances>
<sibling id='0' value='21'/>
<sibling id='1' value='10'/>

<sibling id='3' value='31'/>
</distances>

<cell id='2' cpus='8-11' memory='2097152' unit='KiB'>
<distances>
<sibling id='0' value='31'/>
<sibling id='1' value='21'/>
<sibling id='2' value='10'/>

</distances>
<cell id='3' cpus='12-15' memory='2097152' unit='KiB'>

<sibling id='2' value='21'/>
<sibling id='3' value='10'/>
</distances>
</cell>
</numa>
</cpu>
A <cell> defines a NUMA node. <distances> describes the NUMA distance
from the <cell> to the other NUMA nodes (the <sibling>s). For example,
in above XML description, the distance between NUMA node0 <cell id='0'
...> and NUMA node2 <sibling id='2' ...> is 31.
Valid distance values are '10 <= value <= 255'. A distance value of 10
represents the distance to the node itself. A distance value of 20
represents the default value for remote nodes but other values are
possible depending on the physical topology of the system.
When distances are not fully described, any missing sibling distance
values will default to 10 for local nodes and 20 for remote nodes.
If distance is given for A -> B, then we default B -> A to the same
value instead of 20.

Since the virStorageEncryptionPtr encryption; is a member of
_virStorageSource it really should be allowed to be a subelement
of the disk <source> for various disk formats:
Source{File|Dir|Block|Volume}
SourceProtocol{RBD|ISCSI|NBD|Gluster|Simple|HTTP}
NB: Simple includes sheepdog, ftp, ftps, tftp
That way we can set up to allow the <encryption> element to be
formatted within the disk source, but we still need to be wary
from whence the element was read - see keep track and when it
comes to format the data, ensure it's written in the correct place.
Modify the qemuxml2argvtest to add a parse failure when there is an
<encryption> as a child of <disk> *and* an <encryption> as a child
of <source>.
The virschematest will read the new test files and validate from a

Since the virStorageAuthDefPtr auth; is a member of _virStorageSource
it really should be allowed to be a subelement of the disk <source>
for the RBD and iSCSI prototcols. That way we can set up to allow
the <auth> element to be formatted within the disk source.
Since we've allowed the <auth> to be a child of <disk>, we'll need
to keep track of how it was read so that when writing out we'll know
whether to format as child of <disk> or <source>. For the argv2xml
parsing, let's format under <source> as a preference. Do not allow
<auth> to be both a child of <disk> and <source>.
Modify the qemuxml2argvtest to add a parse failure when there is an
<auth> as a child of <disk> *and* an <auth> as a child of <source>.
Add tests to validate that if the <auth> was found in <source>, then
the resulting xml2xml and xml2arg works just fine. The two new .args
file are exact copies of the non "-source" version of the file.
The virschematest will read the new test files and validate from a

It's possible to define and start a pool with a '.' in the
name; however, when trying to add a volume to a domain using
the storage pool source with a '.' in the storage pool name,
the domain RNG validation fails because RNG uses 'genericName'
which does not allow a '.' in the name.
Domain XML def parsing has a virXMLValidateAgainstSchema which
generates the error. The Storage Pool XML def parsing has no
call to virXMLValidateAgainstSchema. The only Storage Pool name
validation occurs in virStoragePoolDefParseXML to ensure the
name doesn't have a '/' in it and in storagePoolDefineXML to
call virXMLCheckIllegalChars using the same parameter "\n" as
qemuDomainDefineXMLFlags would check after the RNG check
could be succesful.
In order to resolve this, create a poolName definition in
storagecommon.rng that will mimic the domain name regex that
disallows a newline character, but add the "/" in the exclude
list. Then modify the pool and volume source name definitions
to key off that poolName.
