Hi,<div><br></div><div>OpenNebula does not support Remus management. You can read in the links below what OpenNebula offers in terms of fault tolerance [1] and high availability [2].</div><div><br></div><div>Perhaps a tight integration with Remus is not easy, because OpenNebula assumes total control of the VM life-cycle and placement. But you might be able to make OpenNebula tolerate this sudden live-migrations.</div>
<div><br></div><div>Drivers in OpenNebula are implemented with small scripts, you could modify the xen drivers [3] to be aware of the Remus migrations and redirect the actions to the new back-up host. Hooks [4] can be also used to trigger external scripts upon some events of the VM life-cycle, and Host [5] and VM [6] monitoring scripts can be extended to store any relevant information you might need to use in the hooks or xen drivers.</div>
