It is possible to have an environment with an external engine (physical one or as a virtual machine in an external env) and then use a host as the only hypervisor
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: https://www.ovirt.org/documentation/administration_guide/index.html#sect-Pre... <https://www.ovirt.org/documentation/administration_guide/index.html#sect-Preparing_and_Adding_Local_Storage> 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... <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, Jakov
