We can assign a device from the host machine to a guest.
A new command-line option, -pcidevice is added.
For example, to invoke it for an Ethernet device sitting at
PCI bus:dev.fn 04:08.0 with host IRQ 18, use this:
-pcidevice Ethernet/04:08.0-18
The host ethernet driver is to be removed before
Passthrough devices are host machine PCI devices which have
been handed off to the guest. Handle interrupts from these
devices and route them to the appropriate guest irq lines.
The userspace provides us with the necessary information
via the ioctls.
The guest IRQ numbers can change dynamically,

Hi all,
I've recently read about swiftshader, a software 3d renderer for windows.
I tested this on my virtual windows install and the demo's are looking good.
This may not be perfect, but is should allow to play a simple 3d game
inside kvm.

kvm_qemu_init is called in ap_main_loop() , when ap_main_loop() calls
kvm_main_loop_cpu(), kvm_qemu_init() is run for a second time. It should only
be called in kvm_main_loop_cpu().

So this now moves code away from common code to arch specific
kvm_qemu_arch_init(). Also added is a removal of duplicate calls to
kvm_qemu_init_env() in common code.
