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.
In a lot places we use path like this:
$(srcdir)/../src/....

If this enviroment variable is set, the virTestCompareToFile helper

This is useful when adding new test cases, or making changes that

The PortNumber data type is declared to derive from 'short'.
Unfortunately this is an signed type, so validates the range
[-32,768, 32,767] which excludes valid port numbers between
32767 and 65535.
We can't use 'unsignedShort', since we need -1 to be a valid
port number too.
This change is to use 'int' and set an explicit max boundary
instead of relying on the data types' built-in max.
One of the existing tests is changed to use a high port number
to validate the schema.

<target>
<size unit='KiB'>524287</size>
<node>1</node>

This patch preemptively forbids use of the <memory> device in individual
drivers so the users are warned right away that the device is not
supported.
To enable memory hotplug the maximum memory size and slot count need to
be specified. As qemu supports now other units than mebibytes when
specifying memory, use the new interface in this case.
Add a XML element that will allow to specify maximum supportable memory
and the count of memory slots to use with memory hotplug.
To avoid possible confusion and misuse of the new element this patch
also explicitly forbids the use of the maxMemory setting in individual
drivers's post parse callbacks. This limitation will be lifted when the
support is implemented.

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

To make sure that memory is specified add a check that some form of

no longer possible to specify 0KiB as memory size for the VM, but I
don't think it would be any useful to do so. (I can imagine embedded
systems without memory, just registers, but that's far from what libvirt

There was a mess in the way how we store unlimited value for memory

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.

According to the formatstorage.html description for <source> element
and "format" attribute: "All drivers are required to have a default

As it turns out the disk backend did not choose a default value, so I

updating the storage.html backend disk volume driver documentation to

Our documentation isn't 100% clear about hostdev 'managed' attribute usage,

There are some interface types (notably 'server' and 'client')
which instead of allowing the default set of elements and
attributes (like the rest do), try to enumerate only the elements
they know of. This way it's, however, easy to miss something. For
instance, the <address/> element was not mentioned at all. This
resulted in a strange behavior: when such interface was added
into XML, the address was automatically generated by parsing
code. Later, the formatted XML hasn't passed the RNG schema. This
became more visible once we've turned on the XML validation on
domain XML changes: appending an empty line at the end of
formatted XML (to trick virsh think the XML had changed) made
libvirt to refuse the very same XML it formatted.
Instead of trying to find each element and attribute we are
missing in the schema, lets just allow all the elements and
attributes like we're doing that for the rest of types. It's no
harm if the schema is wider than our parser allows.

The macTableManager attribute of a network's bridge subelement tells
libvirt how the bridge's MAC address table (used to determine the
egress port for packets) is managed. In the default mode, "kernel",
management is left to the kernel, which usually determines entries in
part by turning on promiscuous mode on all ports of the bridge,
flooding packets to all ports when the correct destination is unknown,
and adding/removing entries to the fdb as it sees incoming traffic
from particular MAC addresses. In "libvirt" mode, libvirt turns off
learning and flooding on all the bridge ports connected to guest
domain interfaces, and adds/removes entries according to the MAC
addresses in the domain interface configurations. A side effect of
turning off learning and unicast_flood on the ports of a bridge is
that (with Linux kernel 3.17 and newer), the kernel can automatically
turn off promiscuous mode on one or more of the bridge's ports
(usually only the one interface that is used to connect the bridge to
the physical network). The result is better performance (because
packets aren't being flooded to all ports, and can be dropped earlier
when they are of no interest) and slightly better security (a guest
can still send out packets with a spoofed source MAC address, but will
only receive traffic intended for the guest interface's configured MAC
address).
The attribute looks like this in the configuration:
<network>
<name>test</name>
<bridge name='br0' macTableManager='libvirt'/>
...

cases. The functionality behind this knob is added in later patches.
