Hi Kevin, Yeah, I know what you mean when you say very, very difficult. There is some kind of support for emulating IPMI. There are some -device and -chardev magic that I never understood. For basic testing it passes, but I couldn't connect to node with ipmi-tool.
Having physical machines is the best option here, of course, but hardware may be a scarce resource. Also virtualization enables a whole broad gamma of possibilities, like simulating failures, etc...
