Hello,
I downloaded the current xen-unstable sources from 30.11.2005 and made an
make world, make install.
The dom0-Kernel boots successfully, but the domU-kernel cannot open the root
device. I tried also with hda1 instead of sda1, but the result was the same.
Has anybody an idea?
Regards,
Dieter Edinger
