1. A computer implemented method for enabling selective propagation of configuration elements between and among a host having an operating system environment and a plurality of guests, each guest having an operating system environment, based on a policy, the method comprising the steps of: monitoring, by a computer, configuration elements of the host and of at least some guests of the plurality; detecting, by the computer, changes made to at least one of the monitored configuration elements; determining, by the computer, whether to propagate changed configuration elements between operating system environments, based on a policy indicating configuration elements to be propagated between sources and destinations under conditions; determining, by the computer, to propagate, based on the policy, at least one specific changed configuration element originating from a source operating system environment to at least one destination operating system environment; mapping the at least one specific changed configuration element from the source operating system environment to at least one comparable configuration element from the destination operating system environment, wherein a source operating system of a host differs in type from at least one of the destination operating systems of at least one guest; and responsive to determining to propagate the at least one specific changed configuration element originating from the source operating system environment to the at least one destination operating system environment, propagating, by the computer, the at least one specific changed configuration element from the source operating system environment to the at least one destination operating system environment.
