/**
 *  for server configuration needs, it's perhaps better to use (VM,slot) pair
 *  (vm-name, slot) <----> (MAC)
 *
 *  but for client configuration, when server will have MACs at hand, it'd be
 *  easier to requiest options by MAC.
 *  (MAC) <----> (option-list)
 *
 *  Doubts: What should be done if MAC changed for (vm-name, slot), when syncing should?
 *  XML: serialization of dependecy (DHCP options) - (VM,slot) shouldn't be done via MAC in
 *  the middle.
