Abstract: A method and system for optimizing live migration of a virtual machine (VM) from a source server to a destination server where hardware accelerator virtualization is used. Hardware accelerator performance data is obtained while executing a workload on a virtual function at the source server. It is determined whether to transfer the workload from the source server to the destination server based on the hardware accelerator performance data.

The hardware accelerator performance data may include an amount of output data the workload generates and an amount of input data to the workload. The hardware accelerator may be a graphics processing unit (GPU), and the workload may be a GPU workload.

Abstract: A virtual acceleration device is deployed for a physical machine. The physical machine and the virtual acceleration device are interconnected through a high-speed serial bus. A serial port device for the physical machine can be virtualized and implemented on the virtual acceleration device.
