Abstract
Methods and systems for a virtual machine environment are provided. One method includes allocating a memory for storing a dirty pages data structure for tracking writes to a virtual machine memory by an adapter coupled to a computing device and shared by a plurality of virtual machines; initiating a tracking operation by the adapter or a virtual function driver to track writes to the virtual memory; providing access to the dirty pages data structure in response to a query command, while the adapter or the virtual function driver tracks writes to the virtual machine memory; and providing a number of dirty pages within the dirty pages data structure and a pointer the dirty pages data structure by the adapter or the virtual function driver.
