Abstract: An illustrative embodiment disclosed herein is a method including receiving, by a controller virtual machine (CVM) and from a hypervisor, a request to clone a virtual machine (VM) state. The VM state includes a parent state and a snapshot. The method further includes cloning, by the CVM, the parent state and the snapshot to generate a cloned parent state and a cloned snapshot, respectively, and sending, by the CVM and to the hypervisor, data indicating successful cloning of the parent state and the snapshot.

Abstract: An illustrative embodiment disclosed herein is a host device including a plurality of virtual machines and a controller virtual machine configured to compute a plurality of central processing unit (CPU) usages corresponding to the plurality of virtual machines. The controller virtual machine is further configured to compute a total usage as a sum of the plurality of CPU usages and to flag one or more outlier virtual machines of the plurality of virtual machines responsive to one or more exceeding CPU usages of the one or more outlier virtual machines being greater than a threshold usage. The controller virtual machine is further configured to assign weights to the one or more outlier virtual machines and to select, for virtual machine migration, a first outlier virtual machine of the one or more outlier virtual machines responsive to the total usage being greater than a target usage.

Abstract: An illustrative embodiment disclosed herein is a cluster including a plurality of host devices. The plurality of host devices include a first host device. The cluster further includes a cluster controller that receives indication of a contention on the first host device. The cluster controller selects a plurality of candidate host devices among the plurality of host devices based on a plurality of host CPU usages of the plurality of candidate host devices. The cluster controller computes a plurality of projected CPU usages of the plurality of candidate host devices. The cluster controller selects a target host device among the plurality of candidate host devices based on the plurality of projected CPU usages of the plurality of candidate host devices.
