Description
Technical field
The present invention relates to computer application field, particularly a kind of on-line storage moving method, device and server of dummy machine system.
Background technology
Intel Virtualization Technology has been realized the separating and uncoupling of bottom hardware equipment and upper strata operating system and application program, has greatly improved physical resource utilization factor, becomes one of important base layer support technology of cloud computing platform.Compared with traditional physical machine, virtual machine (Virtual Machine, the VM) system building based on Intel Virtualization Technology has better isolation and closure, be more convenient for migration and management.
Dummy machine system migrating technology allows dummy machine system to move to another suitable target physical machine, so that hardware maintenance, centralized management and software upgrading from a source physical machine.The target of dummy machine system migration is the impact reducing as far as possible service, and shortens as far as possible the time of bulk migration and serve stop time.
For the on-line storage migration of dummy machine system, in prior art, mainly contain three kinds of schemes.
A kind of is the scheme of shutting down migration.This scheme be by dummy machine system from source host migration to destination main frame before, first stop the operation of dummy machine system, then the internal storage state of dummy machine system or virtual machine disk file are transferred to destination main frame from source main frame, wherein, the internal storage states that adopt in LAN (Local Area Network) more, in wide area network, the virtual machine disk files that adopt, finally start dummy machine system operation more on destination main frame.Though this scheme is simple, shut down migration and can cause the external service of dummy machine system completely unavailable, make transition process opaque to user.
Another kind is the pre-iteration copy of internal memory scheme.This scheme is mainly through N wheel iteration, except the first round transmits whole internal storage state, other each take turns the internal memory variable quantity that is all transmission after between last round of transmission period.Due in whole transition process only N wheel transmitting procedure need to stop dummy machine system and on the service of operation, therefore, this scheme can significantly reduce the unavailable time of dummy machine system service in transition process, even reaches the stop time of 100ms.But this scheme has following two limitations: first, for keeping the consistance of migration front and back virtual machine disk file content at source and destination, this scheme requires source host and destination host to possess shared network storage; Secondly, although this scheme shutdown is shorter opportunity, iterating of internal memory also can affect the service performance of dummy machine system, especially changes application service more frequently for internal storage state, and this impact may continue the long period.
The scheme of another migration is based on disk mirroring file data migration copy.This scheme implementation is in keeping the operation of source virtual machine system, and original disk file is copied to destination main frame by source host and internal storage state.In this process, the disk file data that changed after migration starts by migration controller record, then stop any magnetic disc i/o access of dummy machine system on source or destination main frame, the data transmission changing, to destination main frame, is finally started dummy machine system in target end-host.This scheme has solved dummy machine system and has moved the restriction to shared network storage, goes for the dummy machine system migration under wan environment.But, this scheme requires to stop any magnetic disc i/o access of dummy machine system to disk storage space in migration handoff procedure, therefore can produce " I/O " hunger phenomenon, cause the application service execution time in dummy machine system to increase, affect service performance, especially in the time that the network bandwidth is not high or disk read-write is comparatively frequent, this affect the duration will be longer.
