Unfortunately, this did not work as well and in addition running the VM was 
painfully slow (as if hardware acceleration was not used). In the syslog I 
found these messages:
May  5 23:01:46 ws2 kernel: kvm: 7133: cpu0 unhandled wrmsr: 0xc0010117 data 0
May  5 23:01:46 ws2 kernel: kvm: 7133: cpu0 unhandled rdmsr: 0xc0010117
May  5 23:01:46 ws2 kernel: kvm: 7133: cpu0 unhandled rdmsr: 0xc0010117

So probably I need a newer kernel as well.

But anyway even with the newer qemu from F11, I saw the same symptoms 
(disconnect, device not visible in guest). I guess I have to wait for F11 and 
check again.

Btw: I took RPMs from F11 because compiling the src.rpms from F11 did not work 
out on F10 (see attachment for error messages).
