Phoenix Lab Overview
NOTE: for the latest version of this doc, see http://ovirt-infra-docs.readthedocs.org/en/latest/
The Poenix Lab infrastructure is composed by (as of today) 10 nodes separated in two roles. The storage servers (2 hosts) and the oVirt host servers (8 hosts).
The access to the servers is restricted to the foreman and jenkins hosts. So you need to access them first and tunnel through to be able to access any of the machines.
When connecting to the VMs through spice you’ll need some special setup so your connections are tunneled trough ssh, the details are here
