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

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.

Set the capability based on qmp query, or qemu version. The qmp query
includes vmport with 2.2, but no longer with 2.3. It lists only
non-machine specific capabilities, so check the qemu version too until a
machine-specific query is supported.
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.
Some tools, such as virt-manager, prefers having the default USB
controller explicit in the XML document. This patch makes sure there
is one. With this patch, it is now possible to switch from USB1 to
USB2 from the release 0.9.1 of virt-manager.
Fix tests to pass with this change.
In virFDStreamOpenFileInternal(), a errfd pipe is opened by
virCommandRunAsync() and given to virFDStreamOpenInternal().
It seems virFDStream should close errfd, just like the other
fd it is given.
This fixes screenshots leaking FDs:

It is important to be able to attach USB redirected devices to a
particular controller (one that supports USB2 for instance).
Without this patch, only the default bus was used.
<redirdev bus='usb' type='spicevmc'>
<address type='usb' bus='0' port='4'/>
</redirdev>
QEMU uses USB bus name "usb.0" when using the legacy -usb argument.
If we want to allow USB devices to specify their addresses with legacy
-usb, we should either in case of legacy bus name drop the 0 from the
address bus, or just drop the 0 from device id. This patch does the
later.
Another solution would be to permit addressing on non-legacy USB
controllers only.
So that devices can be attached to hubs. Example, to attach to first
port of a usb-hub on port 1.
<hub type='usb'>
<address type='usb' bus='0' port='1'/>
</hub>
<input type='mouse' type='usb'>
<address type='usb' bus='0' port='1.1'/>
</hub>
also add a test entry
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
https://bugzilla.redhat.com/show_bug.cgi?id=693661
We try to use that command first when setting a VNC/SPICE password. If
that doesn't work we fallback to the legacy VNC only password
Allow an expiry time to be set, if that doesn't work, throw an error
if they try to use SPICE.
Change since v1:
- moved qemuInitGraphicsPasswords to qemu_hotplug, renamed
to qemuDomainChangeGraphicsPasswords.
- updated what looks like a typo (that appears to work anyway) in
initial patch from Daniel:
- ret = qemuInitGraphicsPasswords(driver, vm,
- VIR_DOMAIN_GRAPHICS_TYPE_SPICE,
- &vm->def->graphics[0]->data.vnc.auth,
- driver->vncPassword);
+ ret = qemuInitGraphicsPasswords(driver, vm,
+ VIR_DOMAIN_GRAPHICS_TYPE_SPICE,
+ &vm->def->graphics[0]->data.spice.auth,
+ driver->spicePassword);
Based on patch by Daniel P. Berrange <berrange@redhat.com>.
