Hi Javier,
I have made one change since my last e-mail. The @opennebula user on Twitter
suggested I change the BUS to "IDE" because the virtual machine might not have
support for the virtio driver. I tried this but it had no effect - I still get
the same error message. The vm output below has this new BUS value, just so you
know.
My VM id is 21, so:
oneadmin@metroplex:/etc/one$ onevm show 21
The output is:
