Following your advice, I noticed that the system could not boot when I
use the guest virtio driver. I then switch back to as far as  version
10.0 with the same bad result. I then remembered that in the past I used
the '.raw' format. Since I am using the qcow2 format (better
performance), I never tried if=virtio for the disk before until I use
the 0.13.0-rc1 version. I tried the release tar file of 0.12.5 /and/
this time with the guest virtio driver, with the same bad result.
Maybe it is the file format? Maybe the virtio disk driver? I have taken
the virtio drivers from the KVM website.

Frans.
