Hey,
there is a new oVirt Node ISO available for testing:
http://resources.ovirt.org/pub/ovirt-3.5-pre/iso/ovirt-node-iso-3.5.0.ovi...
The "low-light" is that the ISO contains the important bits for hosted engine on
Node - but sadly it is affected by a bug, which prevents further testing.
In general Node is slowly converging to a more stable state.
Feel free to test and provide us with feedback via the usual channels over irc and
mailinglists, as well as bugzilla.
Greetings
