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.

QEMUD_CMD_FLAG_PCI_MULTIBUS should be set in the function qemuCapsExtractVersionInfo() The flag QEMUD_CMD_FLAG_PCI_MULTIBUS is used in the function qemuBuildDeviceAddressStr(). All callers get qemuCmdFlags by the function qemuCapsExtractVersionInfo() except that testCompareXMLToArgvFiles() in qemuxml2argvtest.c. So we should set QEMUD_CMD_FLAG_PCI_MULTIBUS in the function qemuCapsExtractVersionInfo() instead of qemuBuildCommandLine() because the function qemuBuildCommandLine() does not be called when we attach a pci device. tests: set QEMUD_CMD_FLAG_PCI_MULTIBUS in testCompareXMLToArgvFiles() set QEMUD_CMD_FLAG_PCI_MULTIBUS before calling qemuBuildCommandLine() as the flags is not set by qemuCapsExtractVersionInfo().

qemu 0.13.0 (at least as built for Fedora 14, and also backported to RHEL 6.0 qemu) supported an older syntax for a spicevmc channel; it's not as flexible (it has an implicit name and hides the chardev aspect), but now that we support spicevmc, we might as well target both variants. * src/qemu/qemu_capabilities.h (QEMUD_CMD_FLAG_DEVICE_SPICEVMC): New flag. * src/qemu/qemu_capabilities.c (qemuCapsParseDeviceStr): Set it correctly. * src/qemu/qemu_command.h (qemuBuildVirtioSerialPortDevStr): Drop declaration. * src/qemu/qemu_command.c (qemuBuildVirtioSerialPortDevStr): Alter signature, check flag.

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: Comment spelling fixes

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. v2: schema: Make listen vs. socket a <choice>

This patch allows for using custom scripts instead of /usr/bin/qemu emulator in domain XML. To do so, one would specify relative path to the custom script in <emulator/>. The path needs to be relative to qemuxml2argvdata directory and it will be transparently made absolute in runtime. The expected command line needs to contain the exact relative path as was used in domain XML. The problem is RelaxNG schema for domain XML only allows for absolute path within <emulator/>. To workaround it, an extra '/' must be added at the beginning of the path. That is, instead of "./qemu.sh" or "../emulator/qemu.sh" one would use "/./qemu.sh" or "/../emulator/qemu.sh". The extra slash is removed before further processing. I don't like this workaround, it's very ugly but it's the best option I was able to come up with. Relaxing domain XML schema is not an option IMO.
