Hi Alex,
i answered in the wrong branch - i am sorry for that.
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
