[one-users] mounting datablocks in a VM

[opennebula at nerling.ch]

Hallo Steven.
You may define target on the onevm template:
DISK   = [  source   = "/exports/base-image/data-disk.windows.raw",
                 target   = "hdb",
                 readonly = "no" ]

I'm not sure but if you do not define it, opennebula defaults to /dev/vd?

MODEL = "virtio" on the disk session would do the magic for virtio.

Best Regards

Marlon Nerling
