Description
Technical field
The present invention relates to virtual machine technique, particularly a kind of method and apparatus for conversion operations system running environment.
Background technology
Along with the development of ic manufacturing technology, the processing power of CPU (central processing unit) (CPU) is in continuous enhancing.Moore's Law shows: when price is constant, open ended transistor size on integrated circuit, about just can double every 18 months, and performance is also by lifting one times.And in most cases, application can not along with hardware synchronization improving performance, for especially true small-scale application, this just makes server resource not to be fully utilized.And use Intel Virtualization Technology to address this problem well.
Intel Virtualization Technology refers to: utilize software and hardware to combine, and physical server is divided into the virtual machine of several isolation, can working procedure and being independent of each other independently on each virtual machine.Intel Virtualization Technology physical resource is accomplished more fine-grained division, thus server resource is more fully utilized, and provides cost savings; Become software operation by the operation of physical hardware, make to dispose, that change, calamity are standby etc. is convenient; Compared to the multiple application program of unit operation, use virtual machine, the environment of application program is consistent with in physical machine, and O&M is simpler.
For cloud computing technology popular at present, Intel Virtualization Technology is exactly one of its core technology." namely infrastructure serve " (Infrastructure as a Service of cloud computing, IAAS) virtual platform is provided, utilize the feature that virtual deployment is succinct fast, user can according to the loading condition of application actual demand, and on platform, application or release virtual machine dynamically increase or reduce computing power easily.
When user is from the environmental transport and transfer of oneself to virtual platform, most hope can be moved smoothly, namely ensure that system is consistent with original with software environment, so just need P2V(Physical toVirtual, physical machine is to virtual machine) and V2V(Virtual to Virtual, virtual machine is to virtual machine) technology.P2V to refer to system from physical machine context conversion to virtual machine environment, makes virtual machine environment consistent with original physical machine environment; V2V refers to virtual machine environment system being transformed into another platform from the virtual machine environment of a platform, makes source and destination virtual machine environment consistent.
For P2V, a kind of typical way makes Ghost mirror image.Ghost is a backup software of Symantec company, supports system partitioning be made into an image file and return to system partitioning from image file.The step that use Ghost software carries out P2V is as follows:
1. the physical machine shutdown carrying out P2V will be needed;
2. prepare one with Ghost software can boot disk, from this disk startup system;
3. enter Ghost software interface, the Ghost mirror image of manufacturing system;
4. certain that the Ghost image copying made can be identified to virtual machine is independently on Physical Extents;
5. select suitable disk size to create virtual machine, the subregion preserving Ghost mirror image is set to an additional disk of virtual machine;
6. from the dish of Ghost software or .iso file start virtual machine;
7., in the Ghost environment in virtual machine, reduce from mirror image;
8. close virtual machine, the subregion coiling and preserve Ghost mirror image is removed from virtual machine; And
9. start virtual machine.
As can be seen here, it is very loaded down with trivial details for using Ghost software to perform P2V, and this is mainly reflected in following several aspect:
1. due to the operation characteristic of Ghost software, the machinery requirement carrying out P2V first shuts down, and starts from the dish with Ghost software;
The final object of 2.P2V is will by system from physical machine environmental transport and transfer to virtual machine environment, Ghost software reaches this purpose by the step of physical machine-> mirror image-> virtual machine, the middle mirror image produced just has not needed after generation virtual machine, but this process adds the time needed for P2V; And
3. image file needs extra storage space to preserve, when the system content that stores in physical machine itself is many, to the storage of image file with copy and waste storage space and IO interface resource.
For V2V, the mode identical with P2V can be adopted, namely also use Ghost software to be moved by the step of virtual machine 1-> mirror image-> virtual machine 2.
Because the disk great majority of virtual machine store with file mode, directly can pass through switching software, a kind of magnetic disk of virtual machine file of platform is directly transformed into the form that another platform can identify.Such as, can by the software virtual machine of VMware(VMware company by qemu-img instrument) the file transform of .vmdk form be the software virtual machine of Xen(Cambridge University exploitation) file of the .raw form that can identify or .qcow2 form.The step that above-mentioned use crossover tool carries out changing is as follows:
1. from the physical machine of source by magnetic disk of virtual machine file copy to object physical machine;
2. the form using disk crossover tool magnetic disk of virtual machine to be converted to object virtual machine platform in object physical machine can to identify;
3. create virtual machine, the disk file obtained after disk being set to format conversion; And
4. start virtual machine.
Use the mode of above-mentioned direct entiredisk form to compared with the mode performing V2V and use Ghost software, simplify a lot.But on the one hand, this mode is not general, that is, suitable conversion software can not be ensured to carry out the conversion of disc format; On the other hand, some magnetic disk of virtual machine is not self-propagation form, for the magnetic disk of virtual machine of this form, the size of data of disk size and storage is irrelevant, if only deposited little data in the disk that capacity is very large, need the magnetic disk of virtual machine of conversion also to remain very large, this brings a large amount of useless IO interface resource consumptions just to conversion and reproduction process.
