qemu: Set QEMU_AUDIO_DRV=none with -nographic On my machine, a guest fails to boot if it has a sound card, but not graphical device/display is configured, because pulseaudio fails to initialize since it can't access $HOME. A workaround is removing the audio device, however on ARM boards there isn't any option to do that, so -nographic always fails. Set QEMU_AUDIO_DRV=none if no <graphics> are configured. Unfortunately this has massive test suite fallout. Add a qemu.conf parameter nographics_allow_host_audio, that if enabled will pass through QEMU_AUDIO_DRV from sysconfig (similar to vnc_allow_host_audio) 2013-08-17 19:30:47 +00:00			`LC_ALL=C PATH=/bin HOME=/home/test USER=test LOGNAME=test QEMU_AUDIO_DRV=none \`

qemu: Use -machine accel=tcg\|kvm when available This is a better interface to choose accelerator than guessing whether we should enable or disable kvm to get the right one. 2013-04-23 14:17:08 +00:00			`-S -machine pc,accel=tcg,usb=off -m 214 -smp 1 -nographic \`
Add USB option capability To avoid the collision for creating USB controllers in machine->init() and -device xx command line, it needs to set usb=off to avoid one USB controller created in machine->init(). So that libvirt can use -device or -usb to create USB controller sucessfully. So QEMU_CAPS_MACHINE_USB_OPT capability is added, and it is for QEMU v1.3.0 onwards which supports USB option.
