I see events in the event log of my 4.2.6.4-1.el7 ovirt engine that say the following. "Client from address "10.1.1.50" is using version 3 of the API, which has been deprecated since version 4.0 of the engine, and will no longer be supported starting with version 4.4. Make sure to update that client to use a supported versions of the API and the SDKs, before upgrading to version 4.4 of the engine." The question I have is the API of what precisely? I am just trying to determine what I need to update on the client machine to be supported. The client machines are using CentOS 7.4 or newer, and remote viewer to bring back windows desktops. I could assume it is "remote viewer" I need to update, but I thought I would ask here and see what is known about this error message. Thank you. -- Jacob Green Systems Admin
