<div dir="ltr">Hi,<div><br></div><div>OpenNebula is not designed to be deployed in an active-active configuration. We cache lots of things from the DB in oned, so two different oned processes will not coordinate.</div><div>
<br></div><div>With the right configuration, however, it is very unlikely that oned will be the cloud bottleneck. This will be even truer in 4.4, as we are adding more tuning parameters to the xml-rpc server [1].</div><div>
You can deploy the Sunstone server behind a load balancer, see [2].</div>
<div><br></div><div>If what you are after is high availability, there are some how-tos in our blog [3] and the community wiki [4].</div><div><br></div><div>Regards</div><div><br></div><div>[1] <a href="http://dev.opennebula.org/issues/2245" target="_blank">http://dev.opennebula.org/issues/2245</a><br>
