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).
