Currently the virDrvConnectOpen method is supposed to handle both
opening an explicit URI and auto-probing a driver if no URI is
given. Introduce a dedicated virDrvConnectURIProbe method to enable the
probing functionality to be split from the driver opening functionality.
It is still possible for NULL to be passed to the virDrvConnectOpen
method after this change, because the remote driver needs special
handling to enable probing of the URI against a remote libvirtd daemon.

Historically we have used a bare lxc:/// URI for connecting to LXC. This
is different from our practice with QEMU, UML, Parallels, Libxl, BHyve
and VirtualBox drivers, which all use a path of '/system' or '/session'
or both.
By making LXC allow '/system', we have fully standardized on the use of
either '/system' or '/session' for all the stateful drivers that run
inside libvirtd.
Support for lxc:/// is of course maintained for back-compat.

Historically we have used a bare xen:/// URI for connecting to the
legacy Xen driver. The new libxl Xen driver follows the new practice
of allowing '/system' as a path, as well as bare '/' for compat with
the old Xen driver.
This documents xen:///system as the preferred format for Xen, leaving
xen:/// as an undocumented feature just for back-compat.

A <cell> defines a NUMA node. <distances> describes the NUMA distance

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.

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.

Since the virStorageAuthDefPtr auth; is a member of _virStorageSource
it really should be allowed to be a subelement of the disk <source>

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>.

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.

However, our apibuild.py script is not able to deal with the
former one. It messes up comments. To fix this couple of things
needs to be done:
a) DO NOT reset self.comment in parseEnumBlock(). This is a
result from our tokenizer. Upon calling token() if it finds a
comment block it stores it in self.comment and returns the next
token (which is not comment). Therefore, if we reset self.comment
we might lose the first comment in the enum block.
b) we need a variable to track if the current enum block uses
value descriptions before or after values. That is if it's type
virEnumA or virEnumB. Depending on that, it we're dealing with
virEnumA type and the current token is a comma ',' we can add the
value into the list as we already have everything needed:

This patch addresses the same aspects on PPC the bug 1103314 addressed
on x86.
PCI expander bus creates multiple primary PCI busses, where each of these
busses can be assigned a specific NUMA affinity, which, on x86 is
advertised through ACPI on a per-bus basis.
For SPAPR, a PHB's NUMA affinities are assigned on a per-PHB basis, and
there is no mechanism for advertising NUMA affinities to a guest on a
per-bus basis. So, even if qemu-ppc manages to get some sort of multi-bus
topology working using PXB, there is no way to expose the affinities
of these busses to the guest. It can only be exposed on a per-PHB/per-domain
basis.
So patch enables NUMA node tag in pci-root controller on PPC.
The way to set the NUMA node is through the numa_node option of
spapr-pci-host-bridge device. However for the implicit PHB, the only way
to set the numa_node is from the -global option. The -global option applies
to all the PHBs unless explicitly specified with the option on the
respective PHB of CLI. The default PHB has the emulated devices only, so
the patch prevents setting the NUMA node for the default PHB.

Commit 6fb5dd4fd8 removed docs/archnetwork.html.in, but
left behind a pointer to it in docs/formatnetwork.html.in.
Update it so that it points to the wiki, which contains
more detailed and recent information anyway.
Start discovering the mediated devices on the host system and format the
attributes for the mediated device into the XML. Compared to the parent
device which reports generic information about the abstract mediated
devices types, a child device only reports the type name it has been
instantiated from and the IOMMU group number, since that's device
specific compared to the rest of the info that can be gathered about
mediated devices at the moment.
This patch introduces both the formatting and parsing routines, updates
nodedev.rng schema, adding a testcase as well.
The resulting mdev child device XML:
<device>
<name>mdev_4b20d080_1b54_4048_85b3_a6a62d165c01</name>
<path>/sys/devices/.../4b20d080-1b54-4048-85b3-a6a62d165c01</path>

The parser had been clearing out *all* suggested device names for
type='direct' (aka macvtap) interfaces. All of the code implementing
macvtap allows for a user-specified device name, so we should allow
it. In the case that an interface name starts with "macvtap" or
"macvlan" though, we do still clear it out, just as we do with "vnet"
(which is the prefix used for automatically generated tap device
names), since those are the prefixes for the names we autogenerate for
macvtap and macvlan devices.

We are currently parsing only rx/frames/max because that's the only
value that makes sense for us. The tun device just added support for
this one and the others are only supported by hardware devices which
we don't need to worry about as the only way we'd pass those to the
domain is using <hostdev/> or <interface type='hostdev'/>. And in
those cases the guest can modify the settings itself.

Creating dummy <change> elements was a workaround for the
HTML DTD not allowing empty <ul> elements, but we can do
better by tweaking the the XSLT stylesheet.
Now that the source file is validated against a schema that
only allows the <code> HTML tag to be used, we can rely on
that assumption to simplify our XSLT stylesheet.
After the release it's necessary to add a new <release> section for the
upcoming release. Add a template so that it does not have to be
compiled over and over again.
Pool types that have the VIR_STORAGE_POOL_SOURCE_NAME flag set
allow omitting the <name> element and instead fill out the pool name
from the <source><name> element.
Relax the schema to make <name> optional for these pools.
Expressing that at least one of these is required is out of scope
of the schema.

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.

This brings the libvirt version of this RNG file in line with the same
file in netcf (as soon as the corresponding patch there is ACKed and

There's no reason to require it when defining an interface (the config

A mediated device will be identified by a UUID (with 'model' now being
a mandatory <hostdev> attribute to represent the mediated device API) of
the user pre-created mediated device. We also need to make sure that if
user explicitly provides a guest address for a mdev device, the address
type will be matching the device API supported on that specific mediated
device and error out with an incorrect XML message.
The resulting device XML:
<devices>
<hostdev mode='subsystem' type='mdev' model='vfio-pci'>
<source>
<address uuid='c2177883-f1bb-47f0-914d-32a22e3a8804'>

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.

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.
