Abstract: Disclosed are various embodiments for distributing the load of a plurality of virtual machines across a plurality of hosts. A potential new host for a virtual machine executing on a current host is identified. A gain rate associated with migration of the virtual machine from the current host to the potential new host is calculated. A gain duration associated with migration of the virtual machine from the current host to the potential new host is also calculated. A migration cost for migration of the virtual machine from the current host to the potential new host, the migration cost being based on the gain rate and the gain duration is determined. It is then determined whether the migration cost is below a predefined threshold cost. Migration of the virtual machine from the current host to the optimal host is initiated in response to a determination that the migration cost is below the predefined threshold.

Abstract: Method, apparatus, and computer program product are provided for dynamically changing containerized workload isolation in response to detection of a triggering factor. In some embodiments, workload is containerized using a default container runtime (e.g., runC) that spawns one or more cgroup-based containers on a compute node using resource limiting capabilities of the compute node's host kernel including cgroups and namespaces. In some embodiments, in response to a triggering factor, such as a host kernel vulnerability, at least some of the containerized workload is migrated from running in the one or more cgroup-based containers to one or more virtual machines (VMs) launched by a standby container runtime (e.g., runV). In some embodiments, the cgroups and namespaces of the one or more cgroup-based containers are live migrated, without service interruption, to one or more VM runtimes on the one or more VMs using CRIU—checkpoint/restore in userspace.

The virtual machine hosting environment may be still further operable to save one or more pending I/O requests generated by the virtual machine in conjunction with pausing the virtual machine and to send the pending I/O request(s) to the remote storage in conjunction with resuming the virtual machine.

Abstract: Examples described here include systems and methods for refreshing the operating system (“OS”) of a device enrolled in a management platform. Execution of a first command file ensures that necessary components of the management platform residing on the device are stored in a partitioned portion of the device hard drive to preserve them during the OS refresh. After a new instance of the OS has been installed, execution of a second command file migrates the necessary components from the partitioned portion of the hard drive to the new OS instance. When the user logs back into the refreshed device, a third command file installs all necessary device management components at the new OS instance and re-enrolls the device with the management platform. In this manner, the OS of a managed device can be refreshed and re-enrolled in the management platform without significant input from a user or administrator.

Abstract: A method includes disabling, by a hypervisor executed by a processing device of a source host system, host system access of a device associated with a virtual machine, wherein disabling the host system access prevents the virtual machine from directly accessing guest memory via the device and prevents the device from causing an interrupt. The method further includes migrating the guest memory associated with the virtual machine from the source host system to a destination host system. Upon migrating the guest memory associated with the virtual machine from the source host system to the destination host system, initiation of the virtual machine is caused on the destination host system.

Abstract: Presented herein are techniques that automate data replication in a cluster by defining and managing logical availability zones. Nodes belonging to a same logical availability zone may be brought down together without impacting data availability. Thus, logical availability zones enable easier data management for events such as when nodes must be brought offline for troubleshooting or upgrading, while also providing resiliency against regional outages. Further, present embodiments define logical availability zones and assign nodes to zones in a manner that reduces the amount of data movement that is necessary, thereby requiring fewer computational resources.

Abstract: A workload optimization system includes a workload manager subsystem that provides a plurality of workloads that each generates a jobs, an agent infrastructure subsystem that includes a first container host hosting a first container having a first agent and that processes jobs generated by at least one of the plurality of workloads, and a workload resource optimization subsystem that monitors a job queue of jobs that were generated by the plurality of workloads and that are to be processed by the first container. The workload resource optimization subsystem then determines whether the job queue satisfies a container generation condition. If so, the workload resource optimization subsystem provides instructions to the first container host to generate a second container that includes a second agent. The workload resource optimization subsystem monitors container host utilization to provide instructions to activate a second container host to provide a third container having a third agent.

Abstract: A producer-consumer technique includes creating a pool of consumer threads. Producer threads can enqueue work items on a work queue. Consumer threads from the consumer pool are activated to process work items on the work queue. Only one consumer thread at time is activated from the consumer pool, the remaining consumer threads in the pool waiting for an activation event. When signaled by a producer thread, the activated consumer thread pops all the work items from the work queue for processing. The activate consumer thread then signals another consumer thread in the consumer pool by generating an activation event. When the consumer thread has processed its work items, it places itself in the consumer pool by blocking to wait for an activation event.
