A method is disclosed, as well as a related system and computer program product, for use with a plurality of networked computing devices comprising a plurality of physical ports. The method comprises determining that a non-volatile memory (NVM) device is removably connected with a first port owned by a first virtual machine associated with a first owning entity, and determining whether the NVM device was previously connected with a second port owned by a second virtual machine associated with a second owning entity. The method further comprises determining whether the NVM device has a predefined association with a first instruction file that specifies one or more restrictions for accessing data stored in the NVM device. The method further comprises providing, to the first virtual machine, access to the data stored in the NVM device in accordance with the one or more restrictions.

An optimizer controller controls a hypervisor optimizer to regulate operation of the optimizer to insure the optimizer does not negatively impact operation of software applications. The optimizer controller monitors applications and application performance to determine whether to turn on or off specific optimization features for specific applications. The optimizer may also notify a user of potential problems. The optimizer controller may utilize optimization rules for specific applications that set the conditions for controlling the optimizer. The rules may be dynamically changed based on observed performance and trends of the applications.
