Abstract: In order to make the processor resources in multiple servers of cluster be utilized to operating system transparently, the processor resources virtualization scheme in distributed virtual machine monitor was proposed. That is to make each server provide a certain amount of virtual processors based on the hardware virtualization technology and present them to guest operating systems, to capture the sensitive instructions that would be executed in the virtual processor and make a simulation of their effect through collaboration between servers, and to ensure that all the virtual processor work exactly. Thereby the low layer resource distribution transparency to the guest operating systems was achieved, and guest operating systems and applications could make use of the process ability of multiple servers without any modification.
