Using LABELs is indeed probably the most suitable option.

I've then filed a feature request
(http://dev.opennebula.org/issues/1292) to ask for the possibility to
define the image's LABELs for DISK image specifications in the VM
template.

One could then define a :
DISK = [ TYPE = fs,
         SIZE = 4096,
         FORMAT = ext3,
         SAVE = yes,
         TARGET = sdh,
         LABEL = opt ]

And one would then use a LABEL=opt in /etc/fstab to be able to mount it.

It would probably be quite easy to add some mkfs.ext3 -L command to
add the ext3 label when the image is created.

Hope this helps,

Best regards,
