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: An example method of migrating a virtualized computing instance between source and destination virtualized computing systems includes executing a first migration workflow in the source virtualized computing system, where a host computer executing the virtualized computing instance is a source host in the first migration workflow and a first mobility agent simulates a destination host in the first migration workflow. The method further includes executing a second migration workflow in the destination virtualized computing system, where a second mobility agent in the destination virtualized computing system simulates a source host in the second migration workflow and a host computer in the destination virtualized computing system is a destination host in the second migration workflow. The method further includes transferring, during execution of the first and second migration workflows, migration data including the virtualized computing instance between the first mobility agent and the second mobility agent over a network.

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: Examples maintain consistency of writes for a plurality of VMs during live migration of the plurality from a source host to a destination host. The disclosure intercepts I/O writes to a migrated VM at a destination host and mirrors the I/O writes back to the source host. This “reverse replication” ensures that the CG of the source host is up to date, and that the source host is safe to fail back to if the migration fails.
Abstract translation: 示例在多个从源主机到目的地主机的实时迁移期间保持对多个VM的写入的一致性。 该披露拦截对目标主机上迁移的VM的I / O写入，并将I / O写入镜像到源主机。 这种“反向复制”确保源主机的CG是最新的，并且源主机是安全的，如果迁移失败，则可以安全地回退。

Abstract: Examples perform live migration of VMs from a source host to a destination host using destructive consistency breaking operations. The disclosure makes a record of a consistency group of VMs on storage at a source host as a fail-back in the event of failure. The source VMs are live migrated to the destination host, disregarding consistency during live migration, and potentially violating the recovery point objective. After live migration of all of the source VMs, consistency is automatically restored at the destination host and the live migration is declared a success.

Abstract: The disclosure describes performing live migration of objects such as virtual machines (VMs) from a source host to a destination host. The disclosure changes the storage environment, directly or through a vendor provider, to active/passive synchronous or near synchronous and, during migration, migrates only data which has not already been replicated at the destination host. The source and destination VMs have concurrent access to storage disks during migration. After migration, the destination VM executes with exclusive access to the storage disks, and the system is returned to the previous storage environment of active/passive asynchronous.
Abstract translation: 该公开内容描述了将诸如虚拟机（VM）的对象从源主机到目的地主机的实时迁移。 本公开将存储环境直接或通过供应商提供者更改为主动/被动同步或接近同步，并且在迁移期间仅迁移目标主机尚未复制的数据。 源和目标VM在迁移期间可以并发访问存储磁盘。 迁移后，目标虚拟机以对存储磁盘的独占访问权执行，并将系统返回到主动/被动异步的先前存储环境。

Abstract: Examples perform live migration of objects such as VMs from a source host to a destination host. The disclosure exposes the contents of the storage disk at the destination host, compares the storage disk of the destination host to the source host, and during migration, migrates only data which is not already stored at the destination host. The source and destination VMs have concurrent access to storage disks during migration. After migration, the destination VM executes, with exclusive access to the storage disks.

Abstract: Embodiments described herein rapidly migrate child virtual machines (VM) by leveraging shared memory resources between parent and child VMs. In a first, proactive phase, parent VMs are migrated to a plurality of potential target hosts. In a second, reactive phase, after a request is received to migrate a child VM to a selected target host, memory blocks that are unique to the child VM are migrated to the selected target host. In some examples, memory blocks are compressed and decompressed as needed. In other examples, the operation environment is modified. Aspects of the disclosure offer a high performance, resource efficient solution that outperforms traditional approaches in areas of software compatibility, stability, quality of service control, resource utilization, and more.
