[one-users] OpenNebula multi-instance issue

[Tino Vazquez]

Dear Jose Manuel,

The setup that you are proposing will indeed pose a problem. The
reason being that OpenNebula assumes an exclusive use of the
resources, so the capacity calculus will be render useless, and this
will end up in poor placement decisions. Moreover, all the OpenNebula
instances will use the same "one-id" notation for VM names, and so
some conflicts may arise when two OpenNebula try to deploy VMs with
the same ID on the same host.

We are currently working on High Availability for OpenNebula, and also
in multi-tier deployments, which will improve ONE's feature set and
also its scalability.

Regards,

-Tino
