I think best bet is to try updating to a newer KVM build - you ought
to be able to pull in the 'qemu-system-x86' RPM from Fedora 11 into

So probably I need a newer kernel as well.

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: 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).
