An iothread for virtio-scsi is a property of the controller. Add a lookup
of the 'virtio-scsi-pci' and 'virtio-scsi-ccw' device properties and parse
the output. For both, support for the iothread was added in qemu 2.4
while support for virtio-scsi in general was added in qemu 1.4.
Modify the various mock capabilities replies (by hand) to reflect the
when virtio-scsi was supported and then specifically when the iothread
property was added. For versions prior to 1.4, use the no device error
return for virtio-scsi. For versions 1.4 to before 2.4, add some data
for virtio-scsi-pci even though it isn't complete we're not looking for
anything specific there anyway. For 2.4 to 2.6, add a more complete reply.

If qemu doesn't support DEVICE_TRAY_MOVED event the code that attempts
to change media would attempt to re-eject the tray even if it wouldn't
be notified when the tray opened. Add a capability bit and skip retrying
for old qemus.
The pxb device is a PCIe expander bus that can be added to any
Q35-based machinetype. A single PCIe port (*not* hotpluggable) is
provided; if more than one device is desired, or if hotplug
support is needed, either a pcie-root-port, or some combination of
pcie-switch-upstream-port and pcie-swith-downstream-ports must be
added to it. It can have a NUMA node number associated with it, as
well as a bus number.
The pxb device is a PCI expander bus that can be added to any
440fx-based machinetype. The PCI bus that is created has 32 standard
PCI slots (hotpluggable). It can have a NUMA node number associated

Add a capability bit for the qemu secret object.
Adjust the 2.6.0-1 caps/replies to add the secret object. For the

Add Spice graphics gl attribute. qemu 2.6 should have -spice gl=on argument to

Add capabilities for virtio-keyboard, virtio-mouse
and virtio-tablet devices:
name "virtio-keyboard-device", bus virtio-bus
name "virtio-keyboard-pci", bus PCI
name "virtio-mouse-device", bus virtio-bus
name "virtio-mouse-pci", bus PCI
name "virtio-tablet-device", bus virtio-bus
name "virtio-tablet-pci", bus PCI
Map both -device and -pci versions of the device to one capability.

qemu 2.5 provides virtio video device. It can be used with -device
virtio-vga for primary devices, or -device virtio-gpu for non-vga
devices. However, only the primary device (VGA) is supported with this
patch.

Traditionally, we pass incoming migration URI on QEMU command line,
which has some drawbacks. Depending on the URI QEMU may initialize its
migration state immediately without giving us a chance to set any
additional migration parameters (this applies mainly for fd: URIs). For
some URIs the monitor may be completely blocked from the beginning until
migration is finished, which means we may be stuck in qmp_capabilities
command without being able to send any QMP commands.
QEMU solved this by introducing "defer" parameter for -incoming command
line option. This will tell QEMU to prepare for an incoming migration
while the actual incoming URI is sent using migrate-incoming QMP
command. Before calling this command we can normally talk to the
monitor and even set any migration parameters which will be honored by
the incoming migration.

As of QEMU 0.9.1 the -drive argument can be used to configure
all disks, so the QEMU driver can assume it is always available
and drop support for -hda/-cdrom/etc.
Many of the tests need updating because a great many were
running without CAPS_DRIVE set, so using the -hda legacy
syntax.
Fixing the tests uncovered a bug in the argv -> xml
convertor which failed to handle disk with if=floppy.

The downstream ports of an x3130-upstream switch can each have one of
these plugged into them (and that is the only place they can be
connected). Each xio3130-downstream provides a single PCIe port that
can have PCI or PCIe devices hotplugged into it. Apparently an entire
set of x3130-upstream + several xio3130-downstreams can be hotplugged
as a unit, but it's not clear to me yet how that would be done, since
qemu only allows attaching a single device at a time.
This device will be used to implement the
"pcie-switch-downstream-port" model of pci controller.
This is the upstream part of a PCIe switch. It connects to a PCIe port
(but not PCI) on the upstream side, and can have up to 31
xio3130-downstream controllers (but no other types of devices)
connected to its downstream side.
This device will be used to implement the "pcie-switch-upstream-port"
model of pci controller.
This is a PCIE "root port". It connects only to a port of the
integrated pcie.0 bus of a Q35 machine (can't be hotplugged), and
provides a single PCIe port that can have PCI or PCIe devices
hotplugged into it.
This device will be used to implement the "pcie-root-port" model of
pci controller.
