ef79fb5b5f conf: add <listen> subelement to domain <graphics> element
Once it's plugged in, the <listen> element will be an optional
replacement for the "listen" attribute that graphics elements already
have. If the <listen> element is type='address', it will have an
attribute called 'address' which will contain an IP address or dns
name that the guest's display server should listen on. If, however,
type='network', the <listen> element should have an attribute called
'network' that will be set to the name of a network configuration to
get the IP address from.

* docs/schemas/domain.rng: updated to allow the <listen> element

* docs/formatdomain.html.in: document the <listen> element and its
  attributes.

* src/conf/domain_conf.[hc]:

  1) The domain parser, formatter, and data structure are modified to
     support 0 or more <listen> subelements to each <graphics>
     element. The old style "legacy" listen attribute is also still
     accepted, and will be stored internally just as if it were a
     separate <listen> element. On output (i.e. format), the address
     attribute of the first <listen> element of type 'address' will be
     duplicated in the legacy "listen" attribute of the <graphic>
     element.

  2) The "listenAddr" attribute has been removed from the unions in
     virDomainGRaphicsDef for graphics types vnc, rdp, and spice.
     This attribute is now in the <listen> subelement (aka
     virDomainGraphicsListenDef)

  3) Helper functions were written to provide simple access
     (both Get and Set) to the listen elements and their attributes.

* src/libvirt_private.syms: export the listen helper functions

* src/qemu/qemu_command.c, src/qemu/qemu_hotplug.c,
  src/qemu/qemu_migration.c, src/vbox/vbox_tmpl.c,
  src/vmx/vmx.c, src/xenxs/xen_sxpr.c, src/xenxs/xen_xm.c

  Modify all these files to use the listen helper functions rather
  than directly referencing the (now missing) listenAddr
  attribute. There can be multiple <listen> elements to a single
  <graphics>, but the drivers all currently only support one, so all
  replacements of direct access with a helper function indicate index
  "0".

* tests/* - only 3 of these are new files added explicitly to test the
  new <listen> element. All the others have been modified to reflect
  the fact that any legacy "listen" attributes passed in to the domain
  parse will be saved in a <listen> element (i.e. one of the
  virDomainGraphicsListenDefs), and during the domain format function,
  both the <listen> element as well as the legacy attributes will be
  output.

98bfdff12c spice: add <clipboard copypaste='yes|no'> option
From a security pov copy and paste between the guest and the client is not
always desirable. So we need to be able to enable/disable this. The best place
to do this from an administration pov is on the hypervisor, so the qemu cmdline
is getting a spice disable-copy-paste option, see bug 693645. Example qemu
invocation:
qemu -spice port=5932,disable-ticketing,disable-copy-paste

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.

abb1570eac Spice: support audio, images and stream compression
This extends the SPICE XML to allow variable compression settings for audio,
images and streaming:
    <graphics type='spice' port='5901' tlsPort='-1' autoport='yes'>
        <image compression='auto_glz'/>
        <jpeg compression='auto'/>
        <zlib compression='auto'/>
        <playback compression='on'/>
    </graphics>

All new elements are optional.

82dfc6f38e qemu: Support vram for video of qxl type
For qemu names the primary vga as "qxl-vga":

  1) if vram is specified for 2nd qxl device:

    -vga qxl -global qxl-vga.vram_size=$SIZE \
    -device qxl,id=video1,vram_size=$SIZE,...

  2) if vram is not specified for 2nd qxl device, (use the default
     set by global):

    -vga qxl -global qxl-vga.vram_size=$SIZE \
    -device qxl,id=video1,...

For qemu names all qxl devices as "qxl":

  1) if vram is specified for 2nd qxl device:

    -vga qxl -global qxl.vram_size=$SIZE \
    -device qxl,id=video1,vram_size=$SIZE ...

  2) if vram is not specified for 2nd qxl device:

    -vga qxl -global qxl-vga.vram_size=$SIZE \
    -device qxl,id=video1,...

"-global" is the only way to define vram_size for the primary qxl
device, regardless of how qemu names it, (It's not good a good
way, as original idea of "-global" is to set a global default for
a driver property, but to specify vram for first qxl device, we
have to use it).

For other qxl devices, as they are represented by "-device", could
specify it directly and seperately for each, and it overrides the
default set by "-global" if specified.

v1 - v2:
  * modify "virDomainVideoDefaultRAM" so that it returns 16M as the
    default vram_size for qxl device.

  * vram_size * 1024 (qemu accepts bytes for vram_size).

  * apply default vram_size for qxl device for which vram_size is
    not specified.

  * modify "graphics-spice" tests (more sensiable vram_size)

  * Add an argument of virDomainDefPtr type for qemuBuildVideoDevStr,
    to use virDomainVideoDefaultRAM in qemuBuildVideoDevStr).

v2 - v3:
  * Modify default video memory size for qxl device from 16M to 24M

  * Update codes to be consistent with changes on qemu_capabilities.*

d9ad8ac392 Add VIR_DIV_UP to divide memory or storage request sizes with round up
Use it in all places where a memory or storage request size is converted
to a larger granularity. This avoids requesting too small memory or storage
sizes that could result from the truncation done by a simple division.

This extends the round up fix in 6002e0406c
to the whole codebase.

Instead of reporting errors for odd values in the VMX code round them up.

Update the QEMU Argv tests accordingly as the original memory size 219200
isn't a even multiple of 1024 and is rounded up to 215 megabyte now. Change
it to 219100 and 219136. Use two different values intentionally to make
sure that rounding up works.

Update virsh.pod accordingly, as rounding down and rejecting are replaced
by rounding up.

b0ef5c5367 Support SPICE channel security options
This extends the SPICE XML to allow channel security options

    <graphics type='spice' port='-1' tlsPort='-1' autoport='yes'>
      <channel name='main' mode='secure'/>
      <channel name='record' mode='insecure'/>
    </graphics>

Any non-specified channel uses the default, which allows both
secure & insecure usage

* src/conf/domain_conf.c, src/conf/domain_conf.h,
  src/libvirt_private.syms: Add XML syntax for specifying per
  channel security options for spice.
* src/qemu/qemu_conf.c: Configure channel security with spice

9b57fa65bd Implement QEMU/KVM support for SPICE graphics
This supports the -spice argument posted for review against
the latest upstream QEMU/KVM. This supports the bare minimum
config with port, TLS port & listen address. The x509 bits are
added in a later patch.

* src/qemu_conf.c, src/qemu_conf.h: Add SPICE flag. Check for
  -spice availability. Format -spice arg for command line
* qemuhelptest.c: Add SPICE flag
* qemuxml2argvdata/qemuxml2argv-graphics-spice.args: Add <graphics>
  for spice
* qemuxml2argvdata/qemuxml2argv-graphics-spice.xml: Add -spice arg
* qemuxml2argvtest.c: Add SPICE flag

635f9ca1f3 Implement QEMU/KVM QXL video card support in QEMU driver
This supports the '-vga qxl' parameter in upstream QEMU/KVM
which has SPICE support added. This isn't particularly useful
until you get the next patch for -spice support. Also note that
while the libvirt XML supports multiple video devices, this
patch only supports a single one. A later patch can add support
for 2nd, 3rd, etc PCI devices for QXL

* src/qemu/qemu_conf.h: Flag for QXL support
* src/qemu/qemu_conf.c: Probe for '-vga qxl' support and implement it
* tests/qemuxml2argvtest.c, tests/qemuxml2xmltest.c,
  tests/qemuxml2argvdata/qemuxml2argv-graphics-spice.args,
  tests/qemuxml2argvdata/qemuxml2argv-graphics-spice.xml: Test
