A hypervisor resource overallocation and dynamic adjustment method and system based on load perception

Abstract

The invention relates to a Hypervisor resource hyper-allocation and dynamic adjusting method and a system based on load awareness. According to the method, the load and hyper-allocation conditions of Hypervisor resources are monitored, the resource hyper-allocation coefficient of each Hypervisor host is set, recorded, and adjusted, the set resource hyper-allocation coefficient of each Hypervisor resource in a cluster is adjusted in a dynamic manner, the resource reusability of Hypervisor is quantified rather than being an empirical value, the allocation of virtual machines in the Hypervisor cluster is migrated so that normal operation of the virtual machines can be guaranteed, the resource utilization rate of Hypervisor is increased, the overall utilization rate of the cloud is increased, and the energy consumption and the maintenance cost are reduced.

Description

technical field [0001] The invention relates to the field of cloud computing management, in particular to a hypervisor resource overallocation and dynamic adjustment method and system based on load perception. Background technique [0002] Hypervisor, an intermediate software layer that runs between the underlying physical server and the operating system, allows multiple operating systems and applications to share hardware. It can also be called VMM (virtual machine monitor), that is, a virtual machine monitor. [0003] Hypervisors are a kind of "meta" operating system in a virtual environment. They have access to all physical devices on the server including disks and memory. [0004] Hypervisors not only coordinate access to these hardware resources, but also impose protection between each virtual machine. When the server starts and executes the hypervisor, it loads the operating system of all virtual machine clients and allocates the appropriate amount of memory, CPU, n...
