bb1c5423b9 spice: support streaming-video parameter
This adds a streaming-video=filter|all|off attribute. It is used to change
the behavior of video stream detection in spice, the default is filter (the
default for libvirt is not to specify it - the actual default is defined in
libspice-server.so).

Usage:

    <graphics type='spice' autoport='yes'>
      <streaming mode='off'/>
    </graphics>

Tested with the above and with tests/qemuxml2argvtest.

a757e60a07 domain.rng vs. formatdomain.html#elementsUSB
The Relax-NG schema for domains regarding <hostdev> doesn't match what's
implemented in src/conf/domain_conf.c#virDomainHostdevDefFormat(): The
implementation only requires @type, but the schema currently either
required none or all three attributes (@mode, @type, and @managed) to be
defined together, because they are declared in the same
<optional)-section. (@managed is currently even undocumented on
<http://libvirt.org/formatdomain.html#elementsUSB>).

Thus the following minimal <hostdev>-example fails to validate:
<domain type='test'>
        <name>N</name>
        <memory>4096</memory>
        <bootloader>/bin/false</bootloader>
        <os>
                <type arch='x86_64' machine='xenpv'>linux</type>
        </os>
        <devices>
                <hostdev type='pci'>
                        <source>
                                <address bus='0x06' slot='0x00' function='0x0'/>
                        </source>
                </hostdev>
        </devices>
</domain>

The schema is changed to match the current implementation:
1. @mode is optional (which defaults to 'subsystem')
2. @type is required
3. @managed is optional (which defaults to 'no')

The documentation is updated to mention @managed.

5754dbd56d Give each virtual network bridge its own fixed MAC address
This fixes https://bugzilla.redhat.com/show_bug.cgi?id=609463

The problem was that, since a bridge always acquires the MAC address
of the connected interface with the numerically lowest MAC, as guests
are started and stopped, it was possible for the MAC address to change
over time, and this change in the network was being detected by
Windows 7 (it sees the MAC of the default route change), so on each
reboot it would bring up a dialog box asking about this "new network".

The solution is to create a dummy tap interface with a MAC guaranteed
to be lower than any guest interface's MAC, and attach that tap to the
bridge as soon as it's created. Since all guest MAC addresses start
with 0xFE, we can just generate a MAC with the standard "0x52, 0x54,
0" prefix, and it's guaranteed to always win (physical interfaces are
never connected to these bridges, so we don't need to worry about
competing numerically with them).

Note that the dummy tap is never set to IFF_UP state - that's not
necessary in order for the bridge to take its MAC, and not setting it
to UP eliminates the clutter of having an (eg) "virbr0-nic" displayed
in the output of the ifconfig command.

I chose to not auto-generate the MAC address in the network XML
parser, as there are likely to be consumers of that API that don't
need or want to have a MAC address associated with the
bridge.

Instead, in bridge_driver.c when the network is being defined, if
there is no MAC, one is generated. To account for virtual network
configs that already exist when upgrading from an older version of
libvirt, I've added a %post script to the specfile that searches for
all network definitions in both the config directory
(/etc/libvirt/qemu/networks) and the state directory
(/var/lib/libvirt/network) that are missing a mac address, generates a
random address, and adds it to the config (and a matching address to
the state file, if there is one).

e9bd5c0e24 Add txmode attribute to interface XML for virtio backend
This is in response to:

   https://bugzilla.redhat.com/show_bug.cgi?id=629662

Explanation

qemu's virtio-net-pci driver allows setting the algorithm used for tx
packets to either "bh" or "timer". This is done by adding ",tx=bh" or
",tx=timer" to the "-device virtio-net-pci" commandline option.

'bh' stands for 'bottom half'; when this is set, packet tx is all done
in an iothread in the bottom half of the driver. (In libvirt, this
option is called the more descriptive "iothread".)

'timer' means that tx work is done in qemu, and if there is more tx
data than can be sent at the present time, a timer is set before qemu
moves on to do other things; when the timer fires, another attempt is
made to send more data. (libvirt retains the name "timer" for this
option.)

The resulting difference, according to the qemu developer who added
the option is:

    bh makes tx more asynchronous and reduces latency, but potentially
    causes more processor bandwidth contention since the cpu doing the
    tx isn't necessarily the cpu where the guest generated the
    packets.

Solution

This patch provides a libvirt domain xml knob to change the option on
the qemu commandline, by adding a new attribute "txmode" to the
<driver> element that can be placed inside any <interface> element in
a domain definition. It's use would be something like this:

    <interface ...>
      ...
      <model type='virtio'/>
      <driver txmode='iothread'/>
      ...
    </interface>

I chose to put this setting as an attribute to <driver> rather than as
a sub-element to <tune> because it is specific to the virtio-net
driver, not something that is generally usable by all network drivers.
(note that this is the same placement as the "driver name=..."
attribute used to choose kernel vs. userland backend for the
virtio-net driver.)

Actually adding the tx=xxx option to the qemu commandline is only done
if the version of qemu being used advertises it in the output of

    qemu -device virtio-net-pci,?

If a particular txmode is requested in the XML, and the option isn't
listed in that help output, an UNSUPPORTED_CONFIG error is logged, and
the domain fails to start.

6cabc0b0d0 qemu: sound: Support intel 'ich6' model
In QEMU, the card itself is a PCI device, but it requires a codec
(either -device hda-output or -device hda-duplex) to actually output
sound. Specifying <sound model='ich6'/> gives us -device intel-hda
-device hda-duplex I think it's important that a simple <sound model='ich6'/>
sets up a useful codec, to have consistent behavior with all other sound cards.

This is basically Dan's proposal of

    <sound model='ich6'>
        <codec type='output' slot='0'/>
        <codec type='duplex' slot='3'/>
    </sound>

without the codec bits implemented.

The important thing is to keep a consistent API here, we don't want some
<sound> devs require tweaking codecs but not others. Steps I see to
accomplishing this:

    - every <sound> device has a <codec type='default'/> (unless codecs are
        manually specified)
    - <codec type='none'/> is required to specify 'no codecs'
    - new audio settings like mic=on|off could then be exposed in
        <sound> or <codec> in a consistent manner for all sound models

v2:
    Use model='ich6'

v3:
    Use feature detection, from eblake
    Set codec id, bus, and cad values

v4:
    intel-hda isn't supported if -device isn't available

v5:

1d9c0a08d9 qemu: Allow serving VNC over a unix domain socket
QEMU supports serving VNC over a unix domain socket rather than traditional
TCP host/port. This is specified with:

<graphics type='vnc' socket='/foo/bar/baz'/>

This provides better security access control than VNC listening on
127.0.0.1, but will cause issues with tools that rely on the lax security
(virt-manager in fedora runs as regular user by default, and wouldn't be
able to access a socket owned by 'qemu' or 'root').

Also not currently supported by any clients, though I have patches for
virt-manager, and virt-viewer should be simple to update.

94234fa2f8 Introduce per-device boot element
Currently, boot order can be specified per device class but there is no
way to specify exact disk/NIC device to boot from.

This patch adds <boot order='N'/> element which can be used inside
<disk/> and <interface/>. This is incompatible with the older os/boot
element. Since not all hypervisors support per-device boot
specification, new deviceboot flag is included in capabilities XML for
hypervisors which understand the new boot element. Presence of the flag
allows (but doesn't require) users to use the new style boot order
specification.

fe053dbea7 Enable tuning of qemu network tap device "sndbuf" size
This is in response to a request in:

   https://bugzilla.redhat.com/show_bug.cgi?id=665293

In short, under heavy load, it's possible for qemu's networking to
lock up due to the tap device's default 1MB sndbuf being
inadequate. adding "sndbuf=0" to the qemu commandline -netdevice
option will alleviate this problem (sndbuf=0 actually sets it to
0xffffffff).

Because we must be able to explicitly specify "0" as a value, the
standard practice of "0 means not specified" won't work here. Instead,
virDomainNetDef also has a sndbuf_specified, which defaults to 0, but
is set to 1 if some value was given.

The sndbuf value is put inside a <tune> element of each <interface> in
the domain. The intent is that further tunable settings will also be
placed inside this element.

     <interface type='network'>
       ...
       <tune>
         <sndbuf>0</sndbuf>

175077fd70 Add XML config switch to enable/disable vhost-net support
This patch is in response to

  https://bugzilla.redhat.com/show_bug.cgi?id=643050

The existing libvirt support for the vhost-net backend to the virtio
network driver happens automatically - if the vhost-net device is
available, it is always enabled, otherwise the standard userland
virtio backend is used.

This patch makes it possible to force whether or not vhost-net is used
with a bit of XML. Adding a <driver> element to the interface XML, eg:

     <interface type="network">
       <model type="virtio"/>
       <driver name="vhost"/>

will force use of vhost-net (if it's not available, the domain will
fail to start). if driver name="qemu", vhost-net will not be used even
if it is available.

If there is no <driver name='xxx'/> in the config, libvirt will revert
to the pre-existing automatic behavior - use vhost-net if it's
available, and userland backend if vhost-net isn't available.

IP addresses and MAC addresses had been defined in the RNG simply as
<text/> meaning that, according to the RNG, any string could go in
there. Of course the C parsing code does a much better job of
validating, but we may as well have this describing the contents

79c27a620a allow memballoon type of none to desactivate it
The balloon device is automatically added to qemu guests if supported,
but it may be useful to desactivate it. The simplest to not change the
existing behaviour is to allow
  <memballoon type="none"/>
as an extra option to desactivate it (it is automatically added if the
memballoon construct is missing for the domain).

change the default behaviour but avoid creating a balloon device if
type="none" is used.

a8f75d2c7d vepa: parsing for 802.1Qb{g|h} XML
This patch parses the following two XML descriptions, one for
802.1Qbg and one for 802.1Qbh, and stores the data internally.
The actual triggering of the switch setup protocol has not been
implemented here but the relevant code to do that should go into
the functions associatePortProfileId() and disassociatePortProfileId().

   <interface type='direct'>
      <source dev='eth0.100' mode='vepa'/>
      <model type='virtio'/>
      <virtualport type='802.1Qbg'>
        <parameters managerid='12' typeid='0x123456' typeidversion='1'
         instanceid='fa9b7fff-b0a0-4893-8e0e-beef4ff18f8f'/>
      </virtualport>
      <filterref filter='clean-traffic'/>
    </interface>

    <interface type='direct'>
      <source dev='eth0.100' mode='vepa'/>
      <model type='virtio'/>
      <virtualport type='802.1Qbh'>
        <parameters profileid='my_profile'/>
      </virtualport>
    </interface>

I'd suggest to use this patch as a base for triggering the setup
protocol with the 802.1Qb{g|h} switch.

Several rounds of changes were made to this patch. The
following is a list of these changes.
- Renamed structure virVirtualPortProfileDef to virVirtualPortProfileParams
  as per Daniel Berrange's request
- Addressing Daniel Berrange's comments:
 - removing macvtap.h's dependency on domain_conf.h by
   moving the virVirtualPortProfileDef structure into macvtap.h
   and not passing virtDomainNetDefPtr to any functions in
   macvtap.c
- Addressed most of Chris Wright's comments:
  - indicating error in case virtualport XML node cannot be parsed
    properly
  - parsing hex and decimal numbers using virStrToLong_ui() with
    parameter '0' for base
  - tgifname (target interface name) variable wasn't necessary
    to pass to openMacvtapTap function anymore
- assigning the virtual port data structure to the virDomainNetDef
  only if it was previously parsed
- make sure that the error code returned by openMacvtapTap() is a negative n
  in case the associatePortProfileId() function failed.
- renaming vsi in the XML to virtualport
- replace all occurrences of vsi in the source as well
- removing mode and MAC address parameters from the functions that
  will communicate with the hareware diretctly or indirectly
- moving the associate and disassociate functions to the end of the
  file for subsequent patches to easier make them generally available
  for export
- passing the macvtap interface name rather than the link device since
  this otherwise gives funny side effects when using netlink messages
  where IFLA_IFNAME and IFLA_ADDRESS are specified and the link dev
  all of a sudden gets the MAC address of the macvtap interface.
- Removing rc = -1 error indications in the case of 802.1Qbg|h setup in case
  we wanted to use hook scripts for the setup and so the setup doesn't fail
  here.
- if instance ID UUID is not supplied it will automatically be generated
  - adapted schema to make instance ID UUID optional
  - added test case
- parser and XML generator have been separated into their own
  functions so they can be re-used elsewhere (passthrough case
  for example)
- Adapted XML parser and generator support the above shown type
  (802.1Qbg, 802.1Qbh).
- Adapted schema to above XML
- Adapted test XML to above XML
- Passing through the VM's UUID which seems to be necessary for
  802.1Qbh -- sorry no host UUID
- adding virtual function ID to association function, in case it's
  necessary to use (for SR-IOV)

aea68ce906 nwfilter: add support for RAPR protocol
This patch adds support for the RARP protocol. This may be needed due to
qemu sending out a RARP packet (at least that's what it seems to want to
do even though the protocol id is wrong) when migration finishes and
we'd need a rule to let the packets pass.

Unfortunately my installation of ebtables does not understand -p RARP
and also seems to otherwise depend on strings in /etc/ethertype
translated to protocol identifiers. Therefore I need to pass -p 0x8035
for RARP. To generally get rid of the dependency of that file I switch
all so far supported protocols to use their protocol identifier in the
-p parameter rather than the string.

I am also extending the schema and added a test case.

- added test case into patch

4ee2b31804 Changes to clock timer XML to match final design.
The clock timer XML is being updated in the following ways (based on
further off-list discussion that was missed during the initial
implementation):

1) 'wallclock' is changed to 'track', and the possible values are 'boot'
 (corresponds to old 'host'), 'guest', and 'wall'.

2) 'mode' has an additional value 'smpsafe'

3) when tickpolicy='catchup', there can be an optional sub-element of
   timer called 'catchup':

   <catchup threshold=123 slew=120 limit=10000/>

Those three values are all longs, always optional, and if they are present,
they are positive. Internally, 0 indicates "unspecified".

* docs/schemas/domain.rng: updated RNG definition to account for changes

* src/conf/domain_conf.h: change the C struct and enums to match changes.

* src/conf/domain_conf.c: timer parse and format functions changed to
                          handle the new selections and new element.

* src/libvirt_private.syms: *TimerWallclock* changes to *TimerTrack*

* src/qemu/qemu_conf.c: again, account for Wallclock --> Track change.

188af565dd Add timer element to domain schema
timers are sub-elements of clocks. A clock can have zero or more
instances of timer. Within the timer, only the name attribute is
required; all other attributes are optional.

A simpler representation of a timer element is:

  <timer name='platform|pit|rtc|hpet|tsc'
         wallclock='host|guest'
         tickpolicy='delay|catchup|merge|discard'
         frequency='123'
         mode='auto|native|emulate|paravirt'
         present='yes|no'/>

frequency is a ulong. All other attributes are simple enums.

e4d7433ef0 Allow a timezone to be specified instead of sync to host timezone
This extends the XML to allow for

  <clock offset='timezone' timezone='Europe/Paris'/>

This is useful if the admin has not configured any timezone on the
host OS, but still wants to synchronize a guest to a specific one.

  'timezone' attribute on clock configuration

b9e2967a5e Add new clock mode allowing variable adjustments
This introduces a third option for clock offset synchronization,
that allows an arbitrary / variable adjustment to be set. In
essence the XML contains the time delta in seconds, relative to
UTC.

  <clock offset='variable' adjustment='123465'/>

The difference from 'utc' mode, is that management apps should
track adjustments and preserve them at next reboot.

* docs/schemas/domain.rng: Schema for new clock mode
* src/conf/domain_conf.c, src/conf/domain_conf.h: Parse
  new clock time delta
* src/libvirt_private.syms, src/util/xml.c, src/util/xml.h: Add

7813a0f81c Add domain support for virtio channel
Add support for virtio-serial by defining a new 'virtio' channel target type
and a virtio-serial controller. Allows the following to be specified in a
domain:

<controller type='virtio-serial' index='0' ports='16' vectors='4'/>
<channel type='pty'>
  <target type='virtio' name='org.linux-kvm.port.0'/>
  <address type='virtio-serial' controller='0' bus='0'/>
</channel>

2073ed6f20 Fix <cpu> element in domain XML schema
The current schema is more permissive than the XML parsing code in
libvirt. Precisely, 'match' attribute is optional in schema while in
reality its use is bound to <model> element:

- <cpu> element without 'match' attribute is allowed only if <topology>
  element is the only child element of <cpu>

- <cpu> element with 'match' attribute requires <model> element to be
  present; <topology> and <feature> elements are optional

The RNG now supports IPv6 and bonds attached to bridges, along with
some other minor tweaks. All test files from netcf have been copied to
the test directory and added to the xml2xml and schema tests (and they
all pass, of course ;-)

ce4896fb65 Allow for CPU topology specification without model
Currently CPU topology may only be specified together with CPU model:
    <cpu match='exact'>
        <model>name</model>
        <topology sockets='1' cores='2' threads='3'/>
    </cpu>

This patch allows for CPU topology specification without the need for
also specifying CPU model:
    <cpu>
        <topology sockets='1' cores='2' threads='3'/>
    </cpu>

'match' attribute and 'model' element are made optional with the
restriction that 'match' attribute has to be set when 'model' is
present.
