Hi,
I wanted to install webSocket proxy on another host, but I got an error when setting up engine.

It's just that you installed all the engine rpms also on the additional host where you are not going to deploy the engine.

Please run

yum remove ovirt-engine-setup-plugin-ovirt-engine

before trying again; it's enough to avoid hitting it and it's also a good idea since you don't need al the engine on the additional websocket proxy host.

I opened a bug to properly fix it:

https://bugzilla.redhat.com/1318986

Thanks for the report.
