Please CMIIW, interrupt reinjection is a way to handle lost ticks, right?Those switches only exist in the qemu-kvm branch. The fact that -enable-kvm has some effect for you makes me think that you tried upstream KVM support (ie. the one that comes with vanilla QEMU), right?
I tried 0.12.3 stable and also qemu git master: http://git.savannah.gnu.org/cgit/qemu.git/log/
It would be interesting to check if you can reproduce the problem also with qemu-kvm(-0.12.3 or git head). As you may also face an issue of the kvm kernel bits, it would be furthermore helpful to check with the latest kernel from kvm.git or the modules build via kvm-kmod as well.
Can you please post links to the different git repositories, since a lot of different repositories exist here (qemu-kvm and kernel).
Thnx. Ciao, Gerhard -- http://www.wiesinger.com/
