the VM started by launch-qemu.sh has a black qemu window

steps to reproduce:
1.download the 20131019-tinycore-netmap.hdd and dd it into a usb stick
2. plug the usb stick into a physical machine and start the machine from the usb
3. choose the second boot item (slow device waitusb=5), I got a xwindow
4. run pre-taps.sh
5. run launch-qemu.sh kvm --tap 01

I got a back window with title of 'qemu'.

How to get the actual console of the VM and I can set the IP of the VM, run 
netperf or netserver in it?

Thanks
