A data instance to be shared by multiple virtual machines is stored at a hypervisor level. A file system driver is provided to each virtual machine. Each virtual machine mounts a file system backed by the data instance, and thus has read access to the data through its mounted file system. A virtual machine is suspended. A copy of the data instance is saved as part of the stored image of the suspended virtual machine. The suspended virtual machine is subsequently restored from the stored image, and the copy of the data instance is present in the restored virtual machine. The copy of the data instance is detected at a hypervisor level, and the restored virtual machine is provided with read access to the data instance through its mounted filed system.
