[PXE] Node configuraiton
As duscussed on IRC (http://echelog.com/logs/browse/project-fifo/1368828000) the following general options are
a) automatic deployment with rules how to do pools/which image to choose b) fully manual deployment: enter mac, enter configuration c) two step deployment: automatic base image, then refine setup manually
// From @kevinmeziere
There is a forth option: -Listen for dhcp requests (but dont respond) from hosts that have not been "provisioned". These hosts could be added to a "pending hypervisors" list. From that list hypervisors could be provisioned by added to a group, or manually. Another option to C would have a base image, that gathered details on the system and then either: Boot to next device Held the system in a state where vms would not be deployed, but network connectivity was still existent, so that fifo could trigger a reboot (useful if changing disk layout ect).
