[one-users] Using Ruby API with OCA gem

[Daniel Molina Aranda]

Hi,

The problem is that the info method returns an OpenNebula error when it
fails. You should change the return statement to:

--8<------
rc = vm_pool.info()

if OpenNebula.is_error?(rc)
     return rc.message
else
     return rc
end
------>8--

I have updated the documentation script [1], if you want to check it.

Hope this helps.
