Hi all, first of all I'm a bit confused: What is the difference between qemu with command line option --enable-kvm and qemu-kvm? It seems to be a difference in code so far, from the performance point of view it seems to be the same... Now my issue that lead me to a git bisect on qemu-kvm: The following commit / merge breaks my windows guest boot sequence and causes resets infinitely: ec757c67c40a56492001487e69272f62144fd124 Merge branch 'upstream-merge' into next Thu, 5 Jan 2012 11:00:07 +0000 (13:00 +0200) Avi Kivity <avi@xxxxxxxxxx> Interesting: qemu with --enable-kvm master and the same command line options as qemu-kvm runs perfect. My command line options are: qemu-system-x86_64 -serial /dev/ttyS2 -readconfig /etc/ich9-ehci-uhci.cfg -device usb-host,bus=ehci.0 -device usb-tablet -drive file=/dev/sda2,cache=off -m 1024 -net nic,macaddr=$MACADDR -net tap,script=/etc/qemu-ifup -no-acpi -monitor stdio -L /usr/X11R6/share/qemu -boot c -localtime Best regards, Erik -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
