Detailed Description
The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The embodiment of the invention has the technical characteristics that: monitoring a state change rate of the virtual machine undergoing live migration, and after determining that the state change rate of the virtual machine is greater than or equal to a state transfer rate of the virtual machine during a live migration process, adjusting one or more resources of the virtual machine to reduce the state change rate of the virtual machine to less than the state transfer rate of the virtual machine. The embodiment of the invention limits the computing resources on the virtual machine in a mode of ensuring that the state change rate of the virtual machine is less than the state transmission rate of the virtual machine. For example, if during live migration the virtual machine is generating more dirty pages than transferred pages, the amount of resources dedicated to the virtual machine (e.g., CPU, memory, network, etc.) is reduced so that the number of transferred pages will be higher than the contaminated pages.

Running virtual machine 1, virtual machine 2 … virtual machine n on the source host 110; running virtual machine a, virtual machine b … virtual machine N on the target host 120; the guest operating system OS operated by each virtual machine comprises Windows, Linux, Solaris and Mac OS; each virtual machine is accessed by one or more clients of one or more networks, including private networks (e.g., local area networks, wide area networks, intranets, etc.), public networks.
On the source host 110, virtual machine 1, virtual machine 2 … virtual machine n are connected to host migration agent 1 through virtual machine monitor 1; on the target host 120, virtual machine a, virtual machine b … virtual machine N is connected to host migration agent 2 through virtual machine monitor 2; wherein, the virtual machine monitor is used for simulating an underlying hardware platform; and the virtual machine resource operation parameter is reduced according to the indication of the host migration agent.
The source host 110 and the target host 120 are respectively connected to a host controller 130; of course, in some virtualization systems, the host controller 130 may reside in a designated host or be part of the source host 110, the target host 120.
The virtual machines are managed by the host controller 130. The host controller 130 includes a migration control agent 131 that is responsible for the migration of virtual machines over a network channel 132. In addition, the source host 110 and the target host 120 include a host migration agent 1 and a host migration agent 2 to assist the migration control agent 131 or directly handle the migration process.
The migrated virtual machine 140 migrates from the source host 110 to the target host 120, and the state of the virtual machine 140 will be transferred between the two hosts, during which transfer the virtual machine 140 is still running on the source host 110.
