  • Patent number: 11016794
    Abstract: Peripheral device access support in a distributed computing resource cluster is described. In one example, an application can be supported in a container on a virtual machine in a distributed computing resource cluster. A need or requisite of the container for access to a peripheral device is identified. A device profile is created for the container and associated with the isolation environment. The device profile can be relied upon to check and confirm the compliance of one or peripheral devices on various host machines in the resource cluster. First, one or more host machines having access to the peripheral device are identified in the resource cluster. Then, a check for compliance of the peripheral device on one or more of the host machines is performed based on the device profile. The container is instantiated for the application on one of the host machines based on the check for compliance.

  • Patent number: 10853121
    Abstract: Examples provide for virtual machine recovery using pooled memory. A shared partition is created on pooled memory accessible by a plurality of virtual machine hosts. A set of memory pages for virtual machines running on the hosts is moved to the shared partition. A master agent polls memory page tables associated with the plurality of hosts for write access. If the master agent obtains write access to a memory page table of a given host, the given host that previously held the write access is identified as a failed host or an isolated host. The virtual machines of the given host enabled to resume from pooled memory are respawned on a new host while maintaining memory state of the virtual machines using data within the pooled memory, including the virtual machine memory pages, memory page table, host profile data, and/or host-to-VM table data.

  • Patent number: 10725804
    Abstract: An example method is provided to maintain state information of a virtual machine in a virtualized computing environment through a self-triggered approach. The method may comprise detecting, by a first host from a cluster in the virtualized computing environment, that the first host is disconnected from a network connecting the first host to a distributed storage system accessible by the cluster. The method may also comprise suspending, by the first host, a virtual machine supported by the first host and storing state information associated with the virtual machine. The method may further comprise selecting a second host from the cluster and migrating the suspended virtual machine to the second host such that the suspended virtual machine is able to resume from suspension on the second host based on the stored state information.

  • Patent number: 10725883
    Abstract: An example method is provided to maintain state information of a virtual machine in a virtualized computing environment through an externally-triggered approach. The method may comprise detecting, by an external entity, that a first host in a cluster is disconnected from a first network connecting the first host to a distributed storage system accessible by the cluster. The method may also comprise instructing the first host to suspend a virtual machine supported by the first host and to store state information associated with the virtual machine. The method may further comprise selecting a second host from the cluster and instructing the first host to migrate the suspended virtual machine to the second host such that the suspended virtual machine is able to resume from suspension on the second host based on the stored state information.

  • Patent number: 10579403
    Abstract: Techniques for placing containers in a cloud (e.g., into virtual machines (“VMs”)) based on container policies. The container policies may specify compute-related qualities, storage-related quality, and/or network-related qualities that are to be met by the underlying software and hardware that supports execution of the virtual machines. A cloud director or other entity receives requests to place containers in a particular virtual machine based on the container policies and directs placement of the virtual machine based on the policies. The cloud director may migrate and/or reconfigure VMs, virtual machine disk files, and/or virtual network interface controllers to satisfy the container placement policy. After placement, the cloud director may disable migration to maintain the VM in a desired state.

  • Patent number: 10282261
    Abstract: Examples provide a pooled memory heartbeat for virtual machine hosts. A virtual controller creates a pooled memory heartbeat file system in a shared memory partition of a pooled memory. An agent running on each host in a plurality of virtual machine hosts updates a heartbeat file at an update time interval to lock the heartbeat file. The lock indicates the heartbeat status for a given host is active. A master agent accesses the shared memory partition to check the heartbeat status of each host in the pooled memory file system. The heartbeat status is used to determine whether a host that has lost pooled memory access, is network isolated, or failed. If the pooled memory heartbeat status for a given host indicates the host is a failed host, the set of virtual machines running on the given host are respawned on another healthier host.

  • Patent number: 10164835
    Abstract: A method to enable container access to a peripheral device, where the container is hosted by a virtual machine running in a first host and the peripheral device is directly connected to a second host, is provided. The method includes determining a bandwidth requirement of the peripheral device, and comparing the bandwidth requirement of the peripheral device to bandwidth allocated to the virtual machine that is hosting the container. If the bandwidth requirement of the peripheral device is higher than a threshold percentage of the bandwidth allocated to the virtual machine, the virtual machine is migrated from the first host computer to the second host computer. On the other hand, if the bandwidth requirement of the peripheral device is lower than the threshold percentage of the bandwidth allocated to the virtual machine, processes are launched to establish a network channel by which the container communicates with the peripheral device.
