Hello again,
I did some more debugging myself:

These two lines are caused by kvm because these functions are called in this
order:
qemu-kvm-0.12.4/qemu-kvm.c#kvm_cpu_exec()
qemu-kvm-0.12.4/qemu-kvm.c#kvm_run()
qemu-kvm-0.12.4/qemu-kvm.c#handle_unhandled()
-22 = -EINVAL == Invalid Argument
The ffffffff is from the Kernel:
linux-2.6.32.17/arch/x86/kvm/svm.c#vmrun_interception()
run->hw.hardware_exit_reason = SVM_EXIT_ERR
That line is executed because the folloing error occured previous to the line:
linux-2.6.32.17/arch/x86/kvm/svm.c#nested_svm_vmrun_msrpm() <- false
linux-2.6.32.17/arch/x86/kvm/svm.c#nested_svm_map() <- NULL
To me this looks like there's a problem with the virtual memory mapping, but
since I know very little about KVMs internal working, I have no idea on how
to proceed. Anybody any idea?
Sincerely
Philipp
PS: As you can see from the 'svm.c', it's on an AMD Athlon(tm) II X2 250
Processor stepping 02.
