      docs: Correct typos in scsi hostdev and address elements · d10a5f58
      由 Eric Farman 提交于 
      The type='scsi' parameter of an address element is ignored
if placed within a hostdev section, and rejected by the XML
schema used by virt-xml-validate. Remove it from the doc,
and correct a typo in the remaining address arguments.

      docs: Fix XML schema handling of LUN address in hostdev tag · c733e973
      由 Eric Farman 提交于 
      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:

  # virt-xml-validate lmb_guest.xml
  Relax-NG validity error : Extra element devices in interleave
  lmb_guest.xml:17: element devices: Relax-NG validity error :
  Element domain failed to validate content
  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.

  # lsscsi -xx
  [0:0:19:0x4022401100000000]  disk    IBM      2107900          3.44 /dev/sda
  # lsscsi
  [0:0:19:1074872354]disk    IBM      2107900          3.44  /dev/sda
  # cat lmb_guest.xml
  <domain type='kvm'>
    <name>lmb_guest</name>
    <memory unit='MiB'>1024</memory>
  ...trimmed...
    <devices>
      <controller type='scsi' model='virtio-scsi' index='0'/>
      <hostdev mode='subsystem' type='scsi'>
        <source>
          <adapter name='scsi_host0'/>
          <address bus='0' target='19' unit='1074872354'/>
        </source>
      </hostdev>
  ...trimmed...

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.

      docs: add domain vmport feature · 208abbcb
      由 Marc-André Lureau 提交于 
      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.

      conf: Adjust the iothreadsched expectations · 4dec8a01
      由 John Ferlan 提交于 
      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.

      conf: Add new domain XML element 'iothreadids' · 93383c1f
      由 John Ferlan 提交于 
      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.

      conf: Add interface to parse and format memory device information · 3e4230d2
      由 Peter Krempa 提交于 
      This patch adds code that parses and formats configuration for memory
devices.

A simple configuration would be:
<memory model='dimm'>
  <target>
    <size unit='KiB'>524287</size>
    <node>0</node>
  </target>
</memory>

A complete configuration of a memory device:
<memory model='dimm'>
  <source>
    <pagesize unit='KiB'>4096</pagesize>
    <nodemask>1-3</nodemask>
  </source>
  <target>
    <size unit='KiB'>524287</size>
    <node>1</node>
  </target>
</memory>

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.

      qemu: Implement setup of memory hotplug parameters · a41185d8
      由 Peter Krempa 提交于 
      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.

      conf: Add support for parsing and formatting max memory and slot count · bffb9163
      由 Peter Krempa 提交于 
      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.

      doc: Fix doc for backingStore · 060f4c66
      由 Deepak Shetty 提交于 
      I spent quite some time figuring that backingStore info
isn't included in the dom xml, unless guest is up and
running. Hopefully putting that in the doc should help.

Also, several people have complained that libvirt reports
a backing file as raw, even though they expected it to be
qcow2; where the culprit is usually the user forgetting to
create the file with qemu-img create -o backing_fmt=qcow2.

This patch adds that info to the doc.

      docs: schema and docs for the midonet virtualport type · a9fbe3b1
      由 Antoni Segura Puimedon 提交于 
      Midonet is an opensource virtual networking that over lays the IP
network between hypervisors. Currently, such networks can be made
with the openvswitch virtualport type.

This patch, defines the schema and documentation that will serve
as basis for the follow up patches that will add support to libvirt
for using Midonet virtual ports for its interfaces. The schema
definition requires that the port profile expresses its interfaceid
as part of the port profile. For that reason, this is part of the
patch too.

      memtune: change the way how we store unlimited value · cf521fc8
      由 Pavel Hrdina 提交于 
      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.
