Try to run QEMU with "-smp 4". > 2) I need to at least have sound working from applications in the guest > with pulseaudio on the Debian host. Is it possible ? Should be possible. Run the configure script before compiling with --audio-drv-list=pa and then make sure to give a soundcard to the guest (e.g. with the -soundhw option). > 3) USB, what is the level of support 2.0 3.0 ? > ( However windo$ 7 cannot really do USB3. so usb-3 is moot anyway) QEMU supports both, e.g. with "-device usb-ehci" for a USB 2.0 controller or with "-device nec-usb-xhci" for a USB 3.0 controller. > 4) What kind of devices can be run through usb ? Do you mean emulated devices? You can get a list with: qemu-system-x86_64 -device help | grep usb Or do you want to pass-through a real device from the host? > The answers to 1-4 will be really helpful to decide if I should even be > using it.

I don't have much clue about Windows, but I think you can change it afterwards - it's like you're changing PCI cards of a real system in that case. HTH, Thomas
