Background technology
According to NIST (National Institute of Standards and Technology, National Institute of Standards and Technology)
Authority definition, the service mode of cloud computing has SPI (i.e. SaaS, PaaS and IaaS) the big class of these three or level.IaaS
(Infrastructure as a Service, infrastructure i.e. services) refers to that consumer passes through Internet can be from perfect calculating
Infrastructure obtains service.It is the utilization to all computing basic facilities that IaaS is supplied to the service of consumer, including processing
CPU, internal memory, storage, network and other basic calculating resource, user can dispose and run any software, including behaviour
Make system and application program.Consumer does not manages or controls any computing basic facility, but can control operating system selection,
Memory space, the application of deployment, it is also possible to (such as router, fire wall, load are equal to obtain conditional networking component
Weighing apparatus etc.) control.
In the embodiment of the present invention, the cloud computing platform under IaaS service mode is referred to as IaaS cloud platform.For provide or
For person uses the enterprise of IaaS cloud platform, during cloud Constructing data center, often leave over a large amount of virtual resources, this
The a little resource bearings core business of each product line of enterprise.In prior art, migrate the side of the IaaS cloud platform that virtual machine arrives
Case is mainly: directly as mirror image, the cloud main frame made is uploaded to IaaS cloud platform, direct base in IaaS cloud platform
Cloud main frame is created in mirror image.
The present inventor finds during invention, and what existing migration scheme existed technical problem is that poor efficiency, main reason is that:
1) not compression before cloud on cloud mirror image, can make migration time significantly elongate, and mirror image is the biggest, the longest；Need
Bright, " upper cloud " described in the embodiment of the present invention refers to upload to the pictute of IaaS cloud platform.
2) create cloud main frame based on above-mentioned big mirror image, IaaS cloud platform typically require first by image download to this locality, enter one

Embodiment of the present invention offer is described in detail below migrates the virtual machine network to the method carrying out practically of IaaS cloud platform
Framework.As in figure 2 it is shown, under cloud computing environment, the virtual resources of enterprise refers to the virtual pool being made up of a large amount of virtual machines,
Some cloud main frames are included, in order to realize quickly existing for enterprise a large amount of virtual resources being automatically migrated to IaaS in IaaS cloud platform
Cloud platform, needs to increase between virtual pool and IaaS cloud platform to migrate working machine, migrates and arrange Migration tools on working machine,
In order to perform the virtual machine migration work to IaaS cloud platform.
Based on the network architecture shown in Fig. 2, by the specific embodiments of virtual machine (vm) migration to IaaS cloud platform, as it is shown on figure 3,
Following preparation was also needed to: migration personnel log in migration working machine, configuration emigration instrument before specific embodiments performs,
Specify virtual machine to be migrated and configuration information thereof, start Migration tools.After preparation completes, comprise the following steps that
S301, Migration tools initialize and migrate environment.
In being embodied as, Migration tools initializes migration environment and specifically includes that by the virtual machine download in virtual pool to the machine (i.e.
Migrate working machine), tissue virtual machine (vm) migration catalogue, prepare cloud environment SDK (Software Development Kit, software
Development kit), prepare virtualized environment, described preparation virtualized environment such as kvm kernel module, configuration QEMU
Nat, configuration virbr0 etc..
S302, initialize virtual machine to be migrated.
Mainly need fstab, dns, network, iface, grub are done initial configuration, it is ensured that virtual machine is put down in IaaS cloud
Can normally start on platform.Further need exist for carrying out system password initialization, facilitate and under abnormal conditions, manually log into row debug.
In this step, key point is: be filled with two instruments of auto_fsck and auto_init, and auto_fsck is autofile system
System fix tool, repairs file system when cloud main frame starts first automatically；Auto_init is auto-initiation handling implement,
Virtual machine does during for starting first some configurations and initialization automatically process, be allowed to become one and can run on IaaS cloud and put down
Cloud main frame on platform.
S303, cloudization virtual machine to be migrated.
Utilize Kvm to start virtual machine, based on two instruments of auto_fsck and auto_init as above, automatically carry out literary composition
Part system is repaired, and virtual machine does some initialization process, i.e. described cloud automatically.A vnc can be opened simultaneously,
Vnc is remote control tool, and vnc is for representing the progress moving to IaaS cloud platform of virtual machine to be migrated, it is simple to migrate
Personnel understand the cloud actual progress of virtual machine.Described initialization processes and specifically includes that installation base tool kit, configuration
Iface, nameserver, network, infrastructure service, selinux, grub, sysctl, ntp, dhcp etc., and dispose some
Company/platform base service.The most also include the important point: carry out cloud host-initiated speed-optimization and process.Virtual machine cloud
During do toggle speed optimization, the toggle speed of cloud main frame can be accelerated.
S304, on-demand resize (being sized) virtual machine to be migrated.
Calculating system disk and the data disks size of virtual machine to be migrated, the hard disk size of on-demand automatic resize virtual machine is to properly
Size.
S305, injection user data.
Automatically the user data in data disks on virtual machine to be migrated is injected into the system disk after virtual machine resize to be migrated
On.
S306, compress virtual machine to be migrated.
Automatically compress on virtual machine to be migrated and have been injected into the system disk of user data to minimum dimension.First press before cloud on cloud mirror image
Contracting, it is ensured that one minimum dimension mirror image of boil down to, the network transmission as far as possible reducing cloud on cloud mirror image is time-consuming.
S307, configuration information based on cloud environment SDK and virtual machine to be migrated create a vacation in IaaS cloud platform
Cloud main frame.
In the embodiment of the present invention, false cloud main frame refers to that the cloud main frame using an empty file mirror image to create is in order to pass through
Replacement cloud host disk file is evaded falling tradition and is caused image download time time-consuming long problem based on mirror image establishment cloud main frame.
Cloud in S308, migration.
False cloud main frame is done power-off operation, then configures according to user, determine the virtual machine (vm) migration to be migrated of Yun Huahou to IaaS
Locally stored or the shared storage of cloud platform.Move to locally stored method: first delete false cloud main frame on local storage
Fixed disk file, hard locally stored to vacation cloud main frame place of ready-made virtual machine system disk file copy on working machine will be migrated
Dish file place catalogue, finally starts false cloud main frame.Move to share storage method: first delete false cloud main frame in shared storage
On fixed disk file, ready-made virtual machine system disk file on working machine will be migrated import to the fixed disk file place of false cloud main frame
In particular storage pool catalogue in distributed storage, finally start false cloud main frame.
