It is possible to have an environment with an external engine (physical

If the storage component has to be provided by that host itself you have
to use local storage based datacenter and storage domains as well:

If you want to retain the default datacenter created during
installation, you have to edit it and set it as "Local" in "Storage
Type" section.
Or you could create a new DC with that setting
There is also the option to install with Self Hosted Engine and use
shared storage (NFS, SAN, iSCSI,...) if you have one available:
https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine_using_the_command_line/index.html#Installing_the_self-hosted_engine_deployment_host_SHE_cli_deploy
<https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine_using_the_command_line/index.html#Installing_the_self-hosted_engine_deployment_host_SHE_cli_deploy>
Or with the same guide use the host storage itself, but as GlusterFS and
eventually extend it later if/when available with other hosts
Of course in that case you loose all the HA functions available at host
level
Idea is to run a single host, which will be used just for some tests.
So, hosted engine on that single host is not a possibility if the
storage will be local storage provided by that single host?
Thanks,
