[one-users] Creating a VM

Hi Travis,

You can use the "-v" option with onevm create. This will print out a
single line with "ID: " followed by the ID assigned to that VM, which
should be easy to parse from a script. Additionally, there is also an
XML-RPC API (http://www.opennebula.org/documentation:rel1.4:api) you
can use to do pretty much everything you can do from the command line
(e.g., there is a "one.vm.allocate" method that will create a VM and
return the assigned VM).

Cheers!
