At least one of a method, a client computing device, and a server computing device for communicating data associated with a virtual machine are described. In one example, a client computing device is communicatively coupled to a network. A first set of data representative of at least a portion of a virtual machine disk image accessible on the network is determined, the first set of data comprising data arranged in a first sequence. From this first set of data, a second set of data is determined for communication to the client computing device over the network, the second set of data comprising at least a portion of the first set of data arranged in a second sequence, the second sequence being different from the first sequence.
