Description
Technical field
The present invention relates to virtual machine technique field, and in particular to a kind of virtual machine (vm) migration using automatic compatible technology is real
Existing method.
Background technology
With developing rapidly for computer technology, many changes, such as parallel computation, net are there occurs in terms of computer calculating
Lattice are calculated, Distributed Calculation, and academia proposed cloud computing model again in recent years.In cloud computing model, resource is shared, and
Reserved according to the request of user., can be in server on the same stage by virtualization technology（Server）Many void are disposed above
Plan machine（VM）, pass through monitor of virtual machine（VMM）Time-sharing multiplex Server resource, to carry out effectively utilizing Server.Often
The service operation of individual user is on a VM, after the request of user goes through, and cloud computing platform must ensure strict to user
The request of user is performed, allows the imperceptible environment residing for oneself of user to be virtual machine, and is considered in real physical machine.
In addition, cloud computing platform also needs to the load between server in dynamic equilibrium cloud computing center, it is to avoid produce some Server
Over-burden.Avoid having excessive virtual machine VM on Server on the same stage, or have excessive identical service（For example there are multiple VM
All it is CPU calculation types or is all IO types）Cause the Server speeds of service excessively slow.Therefore, Server moneys how efficiently to be managed
Source, is the major issue that cloud computing needs to solve.
Effective settling mode is to carry out VM migrations, and current VM dynamic migration is mostly the server monitoring on Server
After arriving, by manually being migrated, and it can only be migrated on identical Server monitors, for example：Identical Xen
Framework or KVM frameworks, can not but be migrated between Xen and KVM.
The content of the invention
The technical problem to be solved in the present invention is：The present invention is for problem above there is provided one kind using automatic compatible skill
The virtual machine (vm) migration implementation method of art.
The technical solution adopted in the present invention is：
Using the virtual machine (vm) migration implementation method of automatic compatible technology, methods described is controlled by being added in cloud computing framework
Module：Central controller, local controller, wherein：Central controller, local controller operate above resource monitor service and
Migration management is serviced；The monitoring resource of system is supervised by the resource in the resource monitor service and local controller in central controller
Control service, which coordinates, to be completed, resource monitor service of the resource monitor service in central controller periodically into local controller
Request is sent, the resource service condition on respective Server is obtained；Resource monitor service in central controller records entirely
The resource service condition of each server of cloud computing center, when resource uses more than some threshold value, system will be by moving
Move management service and initiate dynamic migration operation.
The local resource monitoring service on resource monitor service and each server in central controller is interacted, really
Making which virtual machine needs migration, and determines the home server of migration, when determining source and destination virtual machine, service
During device, system will issue information central and local migration management service.
Methods described is responsible for carrying out the migration of native virtual machine by the source migration management service of local controller, when source mesh
Monitor of virtual machine it is different when, source platform VM is switched to by state converter the VM forms of purpose platform, then be transmitted,
Purpose migration management service is responsible for receiving virtual machine in destination host.
Methods described is responsible for source migration management service and purpose migration management by the migration management service of central controller
The communication and interaction of service, and the resource service condition in monitoring transition process in real time, the speed of migration, example can be controlled at any time
Such as, when the bandwidth in current cloud computing is limited, migration service will control the speed of migration by controlling the bandwidth of migration,
The migration for not influenceing other to complete virtual machine in the case of servicing as far as possible.Sometimes even understand deferred migration, or quickly moved
Move.
Resource monitor service in local controller except monitor the resource service condition of the machine be also recorded for it is local each
The service condition for CPU, internal memory and the network bandwidth of individual virtual machine.
The cpu usage acquisition process is as follows：On the server of cloud computing center, each VM is entered by VMM
Row scheduling, is tracked, VMM can easily obtain each VM and Server CPU is used by the switching to VM virtual machines
Situation.It can be realized by changing VMM correspondence codes.
The internal memory service condition acquisition process is as follows：When VM is created, VMM installs configuration file and distributes quantitative to VM
Internal memory, in fully virtualized VM, when VM uses internal memory, can transfer to VMM to carry out memory management.When VM internal memory uses hair
When raw in short supply, VM use page is carried out to the duplication of exchange area by VMM, internal memory can be then obtained and use nervous VM.
The bandwidth usage acquisition process is as follows：Network interface card in VM, which is all fictionalized, to be come, actual network transmission
It is also that, by calling Server network interface card to be transmitted, the bandwidth that methods described can monitor each VM by VMM makes
Use situation.
Note：VMM virtual machines (VMM Virtual Machine Monitor) it to include planning, deployment, management and optimization empty
Intend the end-to-end functions such as foundation structure；VM virtual machines.
Beneficial effects of the present invention are：
The characteristics of present invention is directed to cloud computing platform, can be migrated between different cloud computing platforms, cloud can be monitored in real time
The resource service condition of the server of each in calculating, can independently choose whether to carry out dynamic migration, can be different virtual
Migrated, the compatibility of this migration greatly improved and flexibility, the process of dynamic migration can be entered between monitor unit
Row implementing monitoring, so as to take the resources such as excessive bandwidth during avoiding dynamic migration.So as to ensure the VM in transition process
Service quality.
