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: Examples perform live migration of VMs from a source host to a destination host. The disclosure changes the storage environment, directly or through a vendor provider, to active/active synchronous 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, and the system is returned to the previous storage environment (e.g., active/active asynchronous).
Abstract translation: 示例执行虚拟机从源主机到目标主机的实时迁移。 本公开将存储环境直接或通过供应商提供者更改为主动/主动同步，并且在迁移期间仅迁移尚未存储在目标主机的数据。 源和目标VM在迁移期间可以并发访问存储磁盘。 迁移后，目标虚拟机通过独占访问存储磁盘执行，并将系统返回到先前的存储环境（例如，主动/主动异步）。

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.

CPC classification number: G06F9/45558 , G06F2009/4557
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: 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.
