That's called "self-hosted-engine"

This is called all-in-one [1].

No. You are not supposed to setup the host from the web interface.
I didn't try that recently, but in the past there were issues similar
to what you wrote below. Please follow the instructions in that page.
Also please note that in 4.0, allinone will be dropped. Systems that
wish to have everything on a single host will need to use hosted-engine.
Also note that people reported locking issues with local nfs mounts, so
it seems like the safest bet for now is to use nested kvm - run a VM to
play the "Host" role, and another VM as an nfs server (or iscsi), and
then either a third VM for the engine, or hosted-engine (meaning, engine
runs inside a VM running inside the first VM).
