Re: [Users] Is it possible to run the node and engine on the same box?

Instead both vdsm and the engine core needs to be pre-built on the node. This is not trivial, as the engine core requires many packages. If we assume you're using standard Fedora to be able to install rpm's, then we come to the next set of issues; co-hosting engine core with vdsm. There are things that need to be taken care of such as- - Adding the same host as a new host into the engine will cause reboot, which is not a good thing to do to the engine core during the installation process of the host.. - Fencing.... the co-hosted machine should not be fenced under any circumstances, in order to protect the engine core. - Networking... networking changes may impact the engine core as well. So here again we need to be careful. To conclude, it is possible to create a co-hosted machine used both by vdsm and engine-core. However, we need to verify the machine is not being rebooted. There are thoughts and maybe some work on achieving it, but it will take some time. -- /d “Funny,” he intoned funereally, “how just when you think life can't possibly get any worse it suddenly does.” --Douglas Adams, The Hitchhiker's Guide to the Galaxy
