Description
Technical field
The present invention relates to virtual machine technique field, more particularly to a kind of virtual machine loads startup method.
Background technology
Virtual machine is a kind of example for restarting an operating system by virtualization technology on physical host, at present cloud
The use of the large-scale promotion of calculating and rise, virtual machine is more and more common, and virtual machine is with conventional physical machine mode start-up operation
System and service comparison, the former is more flexible, delivers more quick.
Inside cloud virtualization, storage service is to provide disk service for virtual machine instance so that the common object of virtual machine picture
Reason machine possesses disk and is written and read like that.It is following several that existing storage service realizes that framework mainly divides with mode：1. local deposit
Storage (magnetic disk of virtual machine service is provided as the physical machine where virtual machine)；2. centralised storage (is individually deposited by an outside
Storage equipment is supplied to virtual machine use by way of network)；3. distributed storage (is deposited by what external multiple storage devices formed
Accumulation is supplied to virtual machine use by way of network).
Two classes can be divided into three kinds of modes above again by being divided according to storage communication mode, and the first kind is：Pass through local system
System, which calls, directly provides service, and it is exactly such mode to be locally stored, and the disk of physical machine provides clothes directly where virtual machine
Business, needs not move through network, such communication efficiency higher, and faster, but such mode is data is only stored in local to speed,
When local device finds that failure is easy to that loss of data can be caused；Second class is：Storage service is provided by way of network, is collected
Chinese style and distributed storage are all that service is provided in a manner of such network, and the benefit of this mode is storage of the data by profession
Equipment preserves, and storage device has more parts of data backups, and data are not easy to lose, but a disadvantage is that because storage service passes through network,
It is compared with the first kind, efficiency decreases.
Most clouds provide the disk service that commercial city has selected the second class to provide the user with virtual machine on the market at present.
The disk service is that the disk of virtual machine is placed on network storage equipment, when virtual machine load starts, is led to
The mode reading disk content of network is crossed to physical machine physical memory, then starts virtual machine instance in physical machine.But in void
Quasi- machine has larger storage read request and flow when startup, and the load for not only affecting virtual machine starts the time, but also
There is moment larger impact to network storage equipment.
Invention content
The purpose of the present invention is：A kind of method that virtual machine load starts is provided, is solved in existing disk service, virtual machine
Start and caused by the load time is long, big problem is impacted to network storage equipment.
The solution that the present invention solves its technical problem is：A kind of virtual machine load startup method, including：By virtual machine
Operating system image file be stored in physical machine disk；Kernel image file in operating system image file is loaded into
In physical machine memory；Start virtual machine.
Further, after starting virtual machine, the disk read-write of virtual machine is rotated back on network memory.
Further, the kernel image file is compressed version file.
Further, the operating system is Linux or Windows.
The beneficial effects of the invention are as follows：The image file of the operating system of virtual machine is saved in local physical machine by this method
In disk, when virtual machine starts, the kernel image file of operating system is loaded into physical machine memory, shortens virtual machine load
The time of disc content is read when startup, simultaneously as kernel image file is smaller relative to whole system image file data volume,
And kernel image file contains required necessary core data when virtual machine starts, and is opened by the kernel image file
Dynamic virtual machine eliminates unnecessary data during virtual machine starts, reduces the data volume of virtual machine reading.So that virtual machine obtains
Quickly to start, the pressure to network storage when virtual machine load starts is reduced.This method can be applied to cloud.
