[one-users] Help with ESX UUIDs with OpenNebula

OpenNebula supports ESX 5.x, so it may be a good idea to update. In
any case, it should work in ESX 4.x as well, can't you name the NFS
based datastore as "0" and "1"? What error is it giving? If there are
errors, you can try creating it with a different name and then
renaming it.

Hope it helps,

-Tino
