Abstract
A system and method include initiating a live migration of a virtual machine from a first host machine to a second host machine. The system and method include copying an initial copy of data stored in a memory of the first host machine to a memory of the second host machine, determining a set of modified data stored in the memory of the first host machine, determining that transferring the set of modified data stored in the memory of the first host machine exceeds a downtime limit, determining that an increased throttling of the virtual machine executing on the first host machine does not exceed a throttling limit, applying the increased throttling to the virtual machine executing on the first host machine, and copying the set of modified data while the increased throttling is applied to the virtual machine executing on the first host machine.
