Abstract: A method for migrating a virtual machine (VM) includes establishing a first connection to a first cloud computing system executing a first VM, and establishing a second connection to a second cloud computing system managed by a second cloud provider, which is different form the first cloud provider. The method further includes instantiating a second VM designated as a destination VM in the second cloud computing system, and installing a migration agent on each of the first VM and the second VM. The migration agents execute a migration process of the first VM to the second VM by (1) iteratively copying guest data from the first VM to the second VM until a switchover criteria of the migration operation is met, and (2) copying a remainder of guest data from the first VM to the second VM when the switchover criteria is met.

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.
