Abstract
Examples perform live migration of virtual machines (VM) from a source host to a destination host. The live migration performs time-consuming operations before the source host is stunned, reducing the downtime apparent to users. Some examples contemplate pre-copying memory from the source VM to the destination VM, and the opening of disks on the destination VM before stunning the source VM.
