First of all, thanks a lot to Jaime for your help yesterday. I did not have
time to test the Xen solution and I simply have one question :
- The image I downloaded from qemu website work. So, what is so special in
the ttylinux image (and in the one you sent me) so that they can not boot?
This is just for my personal knowledge ;)
