[one-users] Xen Paravirtualized error - cfg and template

[Ruben S. Montero]

Hi

Take a look at a file named "deployment.0", it is the .cfg file generated
by OpenNebula. Compare this file with your working cfg file, probably you
are not using the right bus/mapping. OpenNebula uses a disk approach to
automatically set targets (sda, sdb,...) while your template uses a
partition based layout (sda1, sda2...). So probably you'll need to set
TARGET attribute in the Image template or in the VM template in the DISK
attribute.

Cheers

Ruben
