Installed linux-image-3.0.0-10 on domU and dom0. The hvm domU now boots fine.
The oneiric beta1 dvd image is based on linux-image-3.0.0-9 and therefore hangs after the kernel is booted (same behaviour as described above). So the cure for the malfunction must be somewhere in the changelog of linux-image from 3.0.0-9 to 3.0.0-10 and ubuntu should be installable from beta2 or daily image in a hvm domU.
