    Abstract: A method of migrating a virtual machine (VM) having a virtual disk from a source data center to a destination data center includes generating a snapshot of the VM to create a base disk and a delta disk in which writes to the virtual disk subsequent to the snapshot are recorded, and copying the base disk to a destination data store. The method further includes, in response to a request to migrate the VM, preparing a migration specification at the source and transmitting the migration specification to the destination, the migration specification including a VM identifier and a current content ID of the base disk, and determining that a content ID of the copied base disk matches the current content ID of the base disk included in the migration specification and updating the migration specification to indicate that the base disk does not need to be migrated.

    Abstract: Examples perform asynchronous encrypted live migration of virtual machines (VM) from a source host to a destination host. The encryption of the memory blocks of the VM is performed optionally before a request for live migration is received or after said request. The more resource intensive decryption of the memory blocks of the VM is performed by the destination host in a resource efficient manner, reducing the downtime apparent to users. Some examples contemplate decrypting memory blocks of the transmitted VM on-demand and opportunistically, according to a pre-determined rate, or in accordance with parameters established by a user.

    Abstract: Instructions to fork a source VM are received, and execution of the source VM is temporarily stunned. A destination VM is created, and a snapshot of a first virtual disk of the source VM is created. A checkpoint state of the source VM is transferred to the destination VM. The source VM has one or more virtual disks. One or more virtual disks associated with the destination VM are created and reference the one or more virtual disks of the source VM. Execution of the destination VM is restored using the transferred checkpoint state and the virtual disks of the destination VM in a way that allows the source VM to also resume execution. Forking VMs using the described operation provisions destination VMs in a manner that makes efficient use of memory and disk space, while enabling source VMs to continue execution after completion of the fork operation.

    Abstract: Exemplary methods, apparatuses, and systems receive a request to initiate replication of a virtual machine (VM). In response to the request, a copy of the VM disk is exported to a locally attached portable storage device while the VM continues running. In response to receiving indication of the VM disk being imported from the portable storage device locally within a destination data center, the host computer determines VM data within the source data center is different from or not included within the exported copy of the VM disk and transmits the VM data to the destination data center via a network connection while the VM continues running. An indication that the virtual machine data within the destination data center is within a threshold of similarity with virtual machine data within the source data center is transmitted to the destination data center via the network connection.

    Abstract: Embodiments support instant forking of virtual machines (VMs) and state customization. A computing device initiates execution of a first group of services (e.g., identity-independent) in a first VM. A second VM is instantiated from the first VM. The second VM shares memory and storage with the first VM. The computing device customizes the second VM based on configuration data associated with the second VM. A second group of services (e.g., identity-dependent) starts executing on the second VM after configuring the identity of the second VM. Customizing the second VM includes configuring one or more identities of the second VM. In some embodiments, a domain identity is selected from a pool of previously-created identities and applied to the second VM, before bootup completes on the second VM.

    Abstract: The disclosure provides a method for tracking virtual machines (VMs) associated with a plurality of hosts in an inventory. The method generally includes determining to remove a first host of the plurality of hosts, the first host running a first VM, wherein: the first host and a second host are associated with a first host cluster in the inventory; the first host is the associated-host and the registered-host of the first VM in the inventory; determining the first VM is associated with first host cluster based on the associated-host of the first VM being the first host and the first host being associated with the first host cluster; identifying the second host is associated with the first host cluster in the inventory; altering the associated-host of the first VM to the second host and unsetting the registered-host for the first VM in the inventory; and removing the first host.
