  • Patent number: 10705867
    Abstract: A hypervisor-exchange process includes: suspending, by an “old” hypervisor, resident virtual machines; exchanging the old hypervisor for a new hypervisor, and resuming, by the new hypervisor, the resident virtual machines. The suspending can include “in-memory” suspension of the virtual machines until the virtual machines are resumed by the new hypervisor. Thus, there is no need to load the virtual machines from storage prior to the resuming. As a result, any interruption of the virtual machines is minimized. In some embodiments, the resident virtual machines are migrated onto one or more host virtual machines to reduce the number of virtual machines being suspended.

  • Patent number: 10706005
    Abstract: Exemplary methods, apparatuses, and systems include a distributed memory agent within a first node intercepting an operating system request to open a file from an application running on the first node. The request includes a file identifier, which the distributed memory agent transmits to a remote memory manager. The distributed memory agent receives, from the remote memory manager, a memory location within a second node for the file identifier and information to establish a remote direct memory access channel between the first node and the second node. In response to the request to open the file, the distributed memory agent establishes the remote direct memory access channel between the first node and the second node. The remote direct memory access channel allows the first node to read directly from or write directly to the memory location within the second node while bypassing an operating system of the second node.

  • Patent number: 10708261
    Abstract: Disclosed are various examples for enrollment of gateway enrollment for Internet-of-Things (IoT) device management using a client device. In one example, an onboarding token is retrieved using a request for the onboarding token. The request is authenticated based on user credentials. A gateway account is created using a request to create the gateway account that is transmitted to the management service. The request to create the gateway account includes a gateway identifier. The request is authenticated based on the onboarding token. Gateway credentials for the gateway account are relayed from the management service to the gateway. The gateway credentials authenticate communications between the gateway and the management service. The gateway credentials are concealed from users of the client device.

  • Patent number: 10698739
    Abstract: Routers and host machines can host desktops for two or more enterprises. A virtual local area network is established for each enterprise. Each virtual local area network is connected to a plurality of host machines for the enterprise, with each host machine supporting desktops for use by the enterprise. The desktops access computer resources on the enterprise network of the enterprise to which it is connected. Resources within a host machine are shared by having a virtual switch for each enterprise the host machine supports. The virtual switch for an enterprise is connected to the virtual local area network of the enterprise. Desktops in the host machine that are allocated to the enterprise are given network addresses that include the tag for that enterprise. Virtual desktops for different enterprises can be hosted on different partitions of the same host machine.

  • Patent number: 10693806
    Abstract: Virtual computing instances are provisioned with network resource allocation constraints, which may include hard constraints that must be met in order for the virtual computing instances to be created in a host server. Network resources from multiple hosts may be pooled in a virtual switch, and a cloud management system (CMS) may ensure that a network bandwidth reservation for a new virtual computing instance can be accommodated by network bandwidth in the pool that is reserved for communication endpoint traffic. In addition to such CMS-level constraint enforcement, techniques disclosed herein may also enforce network bandwidths constraints at the host level to guarantee that network bandwidth reservation requirements for communication endpoint(s) of a new virtual computing instance can be satisfied by a particular host before creating the virtual computing instance in that host.

  • Patent number: 10693945
    Abstract: Techniques are described for file/folder redirection for virtual desktops using image scanning. A virtual desktop client establishes a web server on the client computing device. The virtual desktop client detects input requesting file/folder redirection and displays a QR code encoded with the IP address of the web server. A mobile device scans the QR code using a digital camera and launches a web browser to establish a connection with the web server. User input is entered on the mobile device, indicating one or more files/folders to be shared with the virtual desktop. The information identifying the selected files/folders is sent to the client computing device. The selected files/folders are registered with the virtual desktop and the virtual desktop locally mounts a corresponding folder. The client computing device receives file I/O operations from the virtual desktop and redirects the file I/O operations to the mobile device over a secured HTTP connection.
