Abstract

A DMA-capable device of a virtualization host stores a DMA write record, indicating a portion of host memory that is targeted by a DMA write operation, in a write buffer accessible from a virtualization management component of the host. The virtualization management component uses the DMA write record to identify a portion of memory to be copied to a target location to save a representation of a state of a particular virtual machine instantiated at the host.
