Hi,
technically you cannot change the boot device once the VM is created.
What you can do is to use the
onevm saveas <vm_id> <disk_id> <image_name>
command to save the disk on which you installed the OS. The image will
be copied back to opennebula after the machine gracefully shutsdown. You
can then create a new VM using that disk to boot.
I think you should add an empty disk to the VM template, so you can
install on that one and opennebula is aware it exists, so it can save it
later.
I hope I answered your question, otherwise dont hesitate to write back,
Hector
