Abstract
A method used by a virtual machine in communication with an external machine includes providing a single sharing page that is shared between a plurality of virtual machines and a particular virtual machine, wherein the particular virtual machine and the plurality of virtual machines run on a same physical machine; writing into the single sharing page a data packet to be sent by the virtual machine to the external machine; scheduling a page swap between the single sharing page and a blank memory page of the particular virtual machine; and sending, to the external machine, the data packet in the memory page of the particular virtual machine subsequent to the page swap.
