Hi Christophe,
If I understand correctly you're trying with the ttylinux image at:
http://dev.opennebula.org/attachments/download/170/ttylinux.tar.gz
correct?
I have downloaded it again and tested it and it works for me. Could it
be that yout image is corrupt?
The md5sum should be:
04c7d00e88fa66d9aaa34d9cf8ad6aaa ttylinux.img
If you're trying this with the correct image, can you send us the
output of virsh dumpxl of the running vm?
virsh -c qemu:///system dumpxl one-<VMID>
Regards,
Jaime
