  • 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.

  • Patent number: 9996440
    Abstract: Examples provide a fault tolerant virtual machine (VM) using pooled memory. When fault tolerance is enabled for a VM, a primary VM is created on a first host in a server cluster. A secondary VM is created on a second host in the server cluster. Memory for the VMs is maintained on a shared partition in pooled memory. The pooled memory is accessible to all hosts in the cluster. The primary VM has read and write access to the VM memory in the pooled memory. The secondary VM has read-only access to the VM memory. If the second host fails, a new secondary VM is created on another host in the cluster. If the first host fails, the secondary VM becomes the new primary VM and a new secondary VM is created on another host in the cluster.

  • Publication number: 20170364422
    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.

  • Publication number: 20170364287
    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.

    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.
