[ovirt-users] Re: How to access the ovirt node individually?

You can SSH into your node and use the |hosted-engine| utility. To quote the documentation:

To see all available commands, run |hosted-engine --help|. For additional information on a specific command, run |hosted-engine --/command/ --help|.

There is also a section on "Booting the Engine Virtual Machine in Rescue Mode", see chapter 3.1.6 here: https://www.ovirt.org/documentation/administration_guide/index.html
