SCHEDULING OF PROCESSES USING A VIRTUAL FILE SYSTEM

摘要

A process can be scheduled between first and second hosts that using a virtual file system that is shared between the hosts can be used. The process, running on a first hypervisor of the first host, can be scheduled to run on a second hypervisor of the second host. A file can be created that includes the data content of the process address space for the file. The file can be mapped address space of the virtual file system. Data from the physical memory of the first host can be transferred to physical memory of the second host using page fault routines.

主权项

1. A system comprising:
first and second hosts that are designed to schedule a process using a virtual file system that is shared between the hosts by:
scheduling the process, running on a first hypervisor of the first host, to run on a second hypervisor of the second host;identifying a process address space for the process;creating a file that includes the data content of the process address space;mapping the file to address space of the virtual file system;generating, in response to the process running on the second hypervisor requesting access to the file, a page fault;determining that the memory access request is for data that is stored in physical memory of the first host; andtransferring, in response to the determining, the data from the physical memory of the first host to physical memory of the second host.
