Frankly, I don't see the difference in there that much. The basic point
in this is -- have a visible node in ovirt-engine on which I can
experiment with (mainly) libvirt.
At first I though I need to have the 'ovirt-node' package installed but
it doesn't seem it's needed now. I searched through the documentation
but I haven't found a lot related to this particular use case.

I'll try this after resolving few other errors unrelated to oVirt. I
though there is some more complicated way through swamps and dragon lair
=) Thanks for showing me the right way!

I wouldn't want to try that, kvm is still not that stable, people say
the guests get stuck after some time and I don't really need anything
running in these machines.
In case you'll try that, good luck.

Once successful, it would be great if you could document your process
in oVirt's wiki, sharing your experience with other users ;)
I'll try to summarize that in case I'll succeed, but now everything
seems very new to me (I mean I don't even know where to click in the
engine's administration portal).
