Abstract
Disclosed is a method, apparatus and a computer program of a virtual execution environment. In one aspect thereof a data processor includes a disk-based storage system and a virtual machine monitor configured to execute a program in a virtual container. The virtual machine monitor is responsive, prior to execution of the application, to record a set of files accessed during a phase change in the disk-based storage system in a manner predetermined to minimize the time needed to retrieve the set of files. The virtual machine monitor is further responsive, at the occurrence of the phase change, or prior to the occurrence of a phase change if the files are prefetched, to retrieve the files from the disk-based storage system. In a further aspect thereof there is provided a server of the virtual execution environment that includes a unit, responsive to receiving notification from the at least one virtual machine monitor of an occurrence of contemporaneous file accesses not associated with a known phase change of a virtual container, for evaluating the occurrence as a candidate phase change and, responsive to the evaluation indicating a presence of a previously unknown phase change, for a…
