Ok I have tried out the PowerPC target with "-accel tcg,thread=multi". What I saw while booting was this message: kernel[0]: USBF: 235.754 AppleUSBOHCI[0x1151000] Watchdog detected dead controller (hcca #: 0, hc #: 836) The maximum host cpu usgae for QEMU went up, but only by 2 percent. Before qemu-system-ppc would use at most 101% of the host CPU. With the accel option, it went up to 104%. My Mac OS X guest was able to boot up and shutdown correctly with your patches. With the i386 target, I did see host CPU usage go up to 120%. That was nice to see. Windows XP and Windows 2000 would not boot to the desktop for some reason. Your patches can be a real game changer for emulation. Please let me know if there is anything else I could do.
