Abstract

A method of processing data on virtualization platform and device, resolving a problem of low performance of a frontend or a backend of a conventional network resulting from frequently waking up a netfront to receive a thread and frequently demounting a DomU. The method comprises: a netback of a Dom0 receives a first data packet transmitted over an event channel on a virtual machine monitor; and after processing the received first data packet and storing the same in a network socket packet buffering queue, if a mode of a thread received by the Dom0 is determined as a polling mode, the netback is not required to wake up the received thread, wherein the polling mode is used to indicate that the received thread is in a non-sleep mode.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data processing method and device in a virtualization platform. Background technique [0002] Virtualization technology is a new type of computing model that supports simultaneous running of multiple isolated virtual environments on a single hardware platform. By deploying different services in these virtual environments, multiple services can be aggregated on a single physical node. [0003] Taking the open source virtualization product XEN as an example, it includes a virtual machine monitor (English: Virtual Machine Monitor, referred to as: VMM), a privileged virtual machine (Domain 0, referred to as: Dom0) and multiple customer virtual machines (Domain U , referred to as: DomU). [0004] VMM runs between the guest virtual machine and the hardware, and both Dom0 and DomU run on the VMM layer. The special feature of Dom0 is that it has management tools for managing o...
