Abstract: A method of enabling “fast” suspend and “rapid” resume of virtual machines (VMs) employs a cache that is able to perform input/output operations at a faster rate than a storage device provisioned for the VMs. The cache may be local to a computer system that is hosting the VMs or may be shared cache commonly accessible to VMs hosted by different computer systems. The method includes the steps of saving the state of the VM to a checkpoint file stored in the cache and locking the checkpoint file so that data blocks of the checkpoint file are maintained in the cache and are not evicted, and resuming execution of the VM by reading into memory the data blocks of the checkpoint file stored in the cache.

Abstract: A management technique for input/output operations (JO) leverages a hypervisor's position as an intermediary between virtual machines (VMs) and storage devices servicing the VMs to facilitate improvements in overall I/O performance for the VMs. According to this new I/O management technique, the hypervisor sends write requests from VMs destined for storage devices to an I/O staging device that provides higher I/O performance than the storage devices, for caching in the I/O staging device in a write-back mode. Once the I/O staging device has received and acknowledged the write request, the hypervisor immediately provides an acknowledgement to the requesting VM. Later on and asynchronously with respect to the write requests from the VMs, the hypervisor reads the write data from the I/O staging device and sends it over to the storage devices for storage therein.

Abstract: User interface virtualization describes a technique for providing a user with access to one computing device from another computing device, while translating the ergonomics of one computer's user interface style into the ergonomics of the other's. An agent running on a remote desktop exchanges metadata and input events with a corresponding client running on a client device that accepts a “touch and swipe” style input. The agent running on the remote desktop may use an interface interaction API or software framework to programmatically manipulate the user interface of the remote desktop and act as a proxy for the corresponding client. The client constructs and displays native graphical user interface elements at the client device that are virtual representations of a corresponding user interface element at the remote desktop, including file dialogs, clipboards, start menus, and task switchers.
