OpenNebula support is provided by an active community on a best-effort basis:
The first resource to check is the documentation
, make sure also to check the specific guides for the storage and virtualization solutions available in your cloud.
The archives for the user mailing list are also a rich source of useful information. You can browse the archive at the mailing lists page
. If you do not find an answer and you have subscribed to the mailing list
you can ask about the problem (and please be specific) on there.
You can also find help in the #opennebula IRC
channel on Freenode
The Community area of this site provides detailed information about the resources available to help you participate in our community.
The OpenNebula team offers support for the last stable release.
