Abstract: A method of migrating a network file copy (NFC) operation from a first host computing device to a second host computing device includes the steps of: transmitting a first request to the first host computing device to execute the NFC operation, wherein the NFC operation comprises transferring data from a shared datastore to another datastore; after transmitting the first request, selecting the second host computing device to complete the NFC operation in place of the first host computing device, and transmitting a second request to the first host computing device to stop executing the NFC operation; after transmitting the second request, detecting a message indicating that the first host computing device completed the copying of a first portion of the data; and in response to the detection of the message, transmitting a third request to the second host computing device to perform the remainder of the NFC operation.

Abstract: Techniques for implementing data plane isolation for VM mobility operations are provided. In one set of embodiments, these techniques include creating a virtual network path between a source host system and a destination host system participating in a VM mobility operation, which allows the host systems to exchange data for carrying out the operation without exposing their physical IP addresses to each other and without requiring the use of intermediate proxies. In certain embodiments, the virtual network path can be dynamically established upon initiation of the VM mobility operation and dynamically rolled back upon operation completion, thereby reducing the overhead of virtual path management.

Abstract: In one set of embodiments, during an initial pre-copying phase, copies of the virtual disks of a VM or VM template can be distributed across one or more datastores, prior to the start of any cloning. This effectively seeds each datastore with a disk pool comprising a certain number of copies of the VM/VM template's virtual disks. Then, at the time of receiving a user request to create k clones from the VM/VM template, up to k copies of the VM/VM template's virtual disks that already reside in the disk pools of one or more target datastores can be moved from those disk pools to the clones' home folders on the target datastores, thereby reducing or eliminating the need to create brand new copies of the virtual disks on demand.

Abstract: Techniques for implementing application-assisted VM provisioning operations, and in particular application-assisted live migration, are provided. In one set of embodiments, a hypervisor of a source host system can notify a guest application that the VM within which the guest application runs will be imminently live migrated from the source host system to a destination host system, prior to actually carrying out the live migration. In response, the guest application can execute one or more remedial actions that mitigate or avoid issues which may arise with respect to its runtime operation when the VM is stunned and switched over to the destination host system.
