Salvatore Orlando 8987499cda Now using vnets instead of network id for creating networks
Fixed issues with vif scripts on 5.6FP1
Fixed ipv6 issue on 5.6FP1
Plus other various fixes and improvements

Starting to remove debug code
NOTE: Network is configured correctly but instances do not start. Possibly indefinite wait occuring on some commands
