Abstract: A system for managing a virtual machine is provided. The system includes a processor configured to initiate a session for accessing a virtual machine by accessing an operating system image from a system disk and monitor read and write requests generated during the session. The processor is further configured to write any requested information to at least one of a memory cache and a write back cache located separately from the system disk and read the operating system image content from at least one of the system disk and a host cache operably coupled between the system disk and the at least one processor. Upon completion of the computing session, the processor is configured to clear the memory cache, clear the write back cache, and reboot the virtual machine using the operating system image stored on the system disk or stored in the host cache.

Abstract: A virtual disk is provided to a computing environment. The virtual disk includes identity information to enable identification of a virtual machine within the computing environment. A size of the virtual disk is increased within the computing environment to enable the virtual disk to act as a storage for the identity information and as a cache of other system data to operate the virtual machine. The virtual machine is booted within the computing environment. The virtual machine is configured to at least access the virtual disk that includes both identity information and caches other system data to operate the virtual machine. Related apparatus, systems, techniques and articles are also described.
