Please take a look into http://thread.gmane.org/gmane.comp.emulators.kvm.devel/68049. It seems to be an IRQ Problem, which relies in kvm/qemu 0.12.5. I did not find a hint, that this is solved in newer versions. Maybe you can point me in the correct direction to solve the IRQ issue, which isn`t there on 'bare metal'. Kind regards, DP
