Description

Technical field [0001] The present invention relates to computer technology, in particular to a multi-channel multi-core server and its central processing unit (CPU) virtualization processing method. Background technique [0002] A multi-core processor (multi-core CPU) system, also known as a chip multi-processor (CMP) system, refers to a multi-processor system composed of multiple processor cores on a single chip. CMP allows threads to be executed in parallel on multiple processor cores, thereby using thread-level parallelism to improve system performance. Multi-channel multi-core server refers to a computer service system that includes multiple multi-core processor chips. [0003] System-level virtualization technology is usually to add a virtual machine monitor (VMM) between the computer hardware and the operating system, and the virtual machine monitor provides virtualization on the underlying hardware to the upper operating system to relieve the gap between the two ’S direct...

Problems solved by technology

[0004] The traditional system-level virtualization technology is based on the full-virtualization principle (full-virtualization), which combines the traditional direct execution and fast dynamic binary translation technology, that is, the virtual machine monitor provides the virtual machine on the entire lower-level hardware to the upper-level operating system. Virtualization, using binary translation technology, but because the virtual machine monitor simulates the entire hardware environment, there is a large system overhead, resulting in low virtualization implementation efficiency

[0005] To this end, a virtualization technology based on the principle of para-virtualization (para-virtualization) is proposed, that is, to partially virtualize the lower-level hardware environment, and at the same time modify some functions of the upper-level operating system to realize multiple virtual machines running on the host machine at the same time. , this method coordinates the relationship between virtualized hardware, physical hardware and operating system to achieve optimized performance and efficiency, but this solution only proposes a solution for single-core processors, and there is no specific solution for multi-channel multi-core servers.
