Hi Yaniv,

Is there a plan to implement active-active HA in the near future? Is there any progress on it since the discussion in August 2013?

No, not at the moment. We feel that Self-Hosted Engine (SHE) is a great solution thus far.

We are working on improving the performance and scale of the engine, to be able to handle more load, more hosts, more VMs, etc.

This is an ongoing work across all components, from VDSM, to engine core, REST API, database calls and more.

Hi All,

In the new architecture page (http://www.ovirt.org/documentation/architecture/architecture/), overall architecture picture shows that engine supports active-active high availability.

This is inaccurate - the engine is not highly available in A/A architecture. I'd appreciate if you could file an issue for it so we'll fix this page.

However, as per engine HA page (http://www.ovirt.org/develop/release-management/features/engine/engine-high-availability/), active-active HA is not supported yet and there are several implementation issues.

So, could anyone give me a brief explanation about discrepancy between these two pages, and about the plan to implement this feature if not implemented yet?

I suggest looking at self-hosted engine, which provides non-A/A high availability for the engine.
Y.

Sunny
