a companion one. Also, when using ich9-uhci2, for example, we are able
to set some sensible defaults, but it might get confusing for the user
as we don't do that for all controller models.

Since an mpath pool contains all the Multipath devices on a host, allowing
more than one defined on a host at a time should be disallowed under the
policy of disallowing duplicate source pools for the host.
Adjust to docs to clarify the Multipath target path value usage for both
the storage driver (only 1 pool per host) and formatstorage references
(ignore the target element in favor of the default target mapping of
/dev/mapper).

Also move the mention of version numbers for the various PCI
controller models up to the end of the sentence where they are first
given, to avoid confusion.
When support for the pcie-root and dmi-to-pci-bridge buses on a Q35
machinetype was added, I was concerned that even though qemu at the
time allowed plugging a PCI device into a PCIe port, that it might not
be supported in the future. To prevent painful backtracking in the
possible future where this happened, I disallowed such connections
except in a few specific cases requested by qemu developers (indicated
in the code with the flag VIR_PCI_CONNECT_TYPE_EITHER_IF_CONFIG).
Now that a couple years have passed, there is a clear message from
qemu that there is no danger in allowing PCI devices to be plugged
into PCIe ports. This patch eliminates
VIR_PCI_CONNECT_TYPE_EITHER_IF_CONFIG and changes the code to always
allow PCI->PCIe or PCIe->PCI connection *when the PCI address is
specified in the config. (For newly added devices that haven't yet
been given a PCI address, the auto-placement still prefers using the
correct type of bus).
In my previous fix (1310b1358) I've tried to solve an ordering
issue. Well, while it worked it has a side effect of keeping a
temporary file around. My patch was buggy in that sense. Solve

Defining a domain with a SCSI disk attached via a hostdev
tag and a source address unit value longer than two digits
causes an error when editing the domain with virsh edit,
even if no changes are made to the domain definition.
The error suggests invalid XML, somewhere:
# virsh edit lmb_guest
error: XML document failed to validate against schema:
Unable to validate doc against /usr/local/share/libvirt/schemas/domain.rng
Extra element devices in interleave
Element domain failed to validate content
The virt-xml-validate tool fails with a similar error:

Relax-NG validity error : Extra element devices in interleave
lmb_guest.xml:17: element devices: Relax-NG validity error :

lmb_guest.xml fails to validate
The hostdev tag requires a source address to be specified,
which includes bus, target, and unit address attributes.
According to the SCSI Architecture Model spec (section
4.9 of SAM-2), a LUN address is 64 bits and thus could be
up to 20 decimal digits long. Unfortunately, the XML
schema limits this string to just two digits. Similarly,
the target field can be up to 32 bits in length, which
would be 10 decimal digits.

Since the reference unit and target fields are used in
several places in the XML schema, create a separate one
specific for SCSI Logical Units that will permit the
greater length. This permits both the validation utility
and the virsh edit command to succeed when a hostdev
tag is included.

When generating the path to the dir for a CIFS/Samba driver, the code
would generate a source path for the mount using "%s:%s" while the
mount.cifs expects to see "//%s/%s". So check for the cifsfs and
format the source path appropriately.
Additionally, since there is no means to authenticate, the mount
needs a "-o guest" on the command line in order to anonymously mount
the Samba directory.
Commit id '887dd362' added support for a netfs pool format type 'cifs'
and 'gluster' in order to add rng support for Samba and glusterfs netfs
pools. Originally, the CIFS type support was added as part of commit
id '61fb6979'. Eventually commit id 'b325be12' fixed the gluster rng
definition to match expectations.
As it turns out the CIFS rng needed a similar change since the directory
path is not an absDirPath, rather just a dirPath will be required.

The XML parser sets a default <mode> if none is explicitly passed in.
This is then used at pool/vol creation time, and unconditionally reported
in the XML.
The problem with this approach is that it's impossible for other code
to determine if the user explicitly requested a storage mode. There
are some cases where we want to make this distinction, but we currently
can't.
Handle <mode> parsing like we handle <owner>/<group>: if no value is
passed in, set it to -1, and adjust the internal consumers to handle
it.
- Don't redocument the permissions fields for backingstore, just point to
the volume docs.
- Clarify that owner/group are inherited from the parent directory at
volume create/pool build time.
- Clarify that <permissions> fields report runtime values too

Remove the check for the source host name for iSCSI source XML processing
declaring duplicate sources when the source device path and if present the
initiator of a proposed storage pool matches an existing storage pool.
The backend iSCSI storage driver uses 'iscsiadm --mode session' to query
available iscsid target sessions. The output displayed is the IP address
and the IQN (target path) of known targets. The displayed IP address
is a resolved address based on the session --login. Additionally, iscsid
keeps track of the various ways to define the host name (IPv4 Address,
IPv6 Address, /etc/hosts, etc.) for that IQN (see output of an 'iscsiadm
--mode node'). If an incoming IQN matches and the host name provided by
libvirt is resolved to the existing IQN, then iscsid will "reuse" the
session. Although libvirt could do the same name resolution, if there
is a difference, iscsid could still declare two seemingly different sources
to be the same and not create a new session which means libvirt now has
two storage pools looking at the same source. Thus to avoid any strange
host name resolution issues, just rely on iscsid for that and do not
allow multiple pools on the same host to use the same device path (IQN).

A new feature that can be turned on or off.
The QEMU machine vmport option allows to set the VMWare IO port
emulation. This emulation is useful for absolute pointer input when the
guest has vmware input drivers, and is enabled by default for kvm.
However it is unnecessary for Spice-enabled VM, since the agent already
handles absolute pointer and multi-monitors. Furthermore, it prevents
Spice from switching to relative input since the regular ps/2 pointer
driver is replaced by the vmware driver. It is thus advised to disable
vmport when using a Spice VM. This will permit the Spice client to
switch from absolute to relative pointer, as it may be required for
certain games or applications.
The phyp driver stuffed it into a DomainDefPtr during its attachdevice
routine, but the value is never advertised via capabilities so it should
be safe to drop.
Have the phyp driver use OSTYPE_LINUX, which is what it advertises via
capabilities.
With iothreadid's allowing any 'id' value for an iothread_id, the
iothreadsched code needs a slight adjustment to allow for "any"
unsigned int value in order to create the bitmap of ids that will
have scheduler adjustments. Adjusted the doc description as well.
Remove the iothreadspin array from cputune and replace with a cpumask
to be stored in the iothreadids list.
Adjust the test output because our printing goes in order of the iothreadids
list now.
Adding a new XML element 'iothreadids' in order to allow defining
specific IOThread ID's rather than relying on the algorithm to assign
IOThread ID's starting at 1 and incrementing to iothreads count.
This will allow future patches to be able to add new IOThreads by
a specific iothread_id and of course delete any exisiting IOThread.
Each iothreadids element will have 'n' <iothread> children elements
which will have attribute "id". The "id" will allow for definition
of any "valid" (eg > 0) iothread_id value.
On input, if any <iothreadids> <iothread>'s are provided, they will
be marked so that we only print out what we read in.
On input, if no <iothreadids> are provided, the PostParse code will
self generate a list of ID's starting at 1 and going to the number
of iothreads defined for the domain (just like the current algorithm
numbering scheme). A future patch will rework the existing algorithm
to make use of the iothreadids list.
On output, only print out the <iothreadids> if they were read in.

The PortNumber data type is declared to derive from 'short'.
Unfortunately this is an signed type, so validates the range

32767 and 65535.
We can't use 'unsignedShort', since we need -1 to be a valid

This change is to use 'int' and set an explicit max boundary
instead of relying on the data types' built-in max.

Now that the size of guest's memory can be inferred from the NUMA

There was a mess in the way how we store unlimited value for memory
limits and how we handled values provided by user. Internally there
were two possible ways how to store unlimited value: as 0 value or as
VIR_DOMAIN_MEMORY_PARAM_UNLIMITED. Because we chose to store memory
limits as unsigned long long, we cannot use -1 to represent unlimited.
It's much easier for us to say that everything greater than
VIR_DOMAIN_MEMORY_PARAM_UNLIMITED means unlimited and leave 0 as valid
value despite that it makes no sense to set limit to 0.
Remove unnecessary function virCompareLimitUlong. The update of test
is to prevent the 0 to be miss-used as unlimited in future.

Adding functionality to libvirt that will allow it
query the ethtool interface for the availability
of certain NIC HW offload features
Here is an example of the feature XML definition:
<device>
<name>net_eth4_90_e2_ba_5e_a5_45</name>
<path>/sys/devices/pci0000:00/0000:00:03.0/0000:08:00.1/net/eth4</path>
<parent>pci_0000_08_00_1</parent>
<capability type='net'>
<interface>eth4</interface>
<address>90:e2:ba:5e:a5:45</address>
<link speed='10000' state='up'/>
<feature name='rx'/>
<feature name='tx'/>
<feature name='sg'/>
<feature name='tso'/>
<feature name='gso'/>
<feature name='gro'/>
<feature name='rxvlan'/>
<feature name='txvlan'/>
<feature name='rxhash'/>
<capability type='80203'/>
</capability>
</device>

In commit edd1295e1d I've introduced an
XML element that allows to configure state of the network interface
link. Somehow the RNG schema hunk ended up in a weird place in the
network schema definition. Move it to the right place and add a test
case.
Note that the link state is set up via the monitor at VM startup so I
originally didn't think of adding a test case.

According to the formatstorage.html description for <source> element
and "format" attribute: "All drivers are required to have a default
value for this, so it is optional."
As it turns out the disk backend did not choose a default value, so I
added a default of "msdos" if the source type is "unknown" as well as
updating the storage.html backend disk volume driver documentation to
indicate the default format is dos.
Our documentation isn't 100% clear about hostdev 'managed' attribute usage,
because it only makes sense to use it with PCI devices, yet we format
this attribute to all hostdev devices. By adding a note into the docs,
we can possibly avoid confusion from customer's side and also avoid a solution
using ternary logic.

As reported on the libvirt-users list [1], there's new web
application called mist.io which uses libvirt as one of its
backends. Lets add it into our list of libivrt based
applications.
