Description
Technical field
The present invention relates to the communications field, in particular to a kind of virtual machine upgrade method and device.
Background technology
Intel Virtualization Technology application is increasingly extensive, and virtual machine is based on can the mode based on shared father's mirror image in virtual disk, correlation technique
Disposed, Fig. 1 is father and son's mirror schematic diagram according to correlation technique, as shown in figure 1, A1 is father's mirror image, A2, A3
It is sub- mirror image with A4, V1, V2 and V3 are virtual machine, and each virtual machine is articulated on corresponding sub- mirror image, but virtual machine
Basic operation program and data are all placed in father's mirror image, and the delta data of virtual machine is placed in sub- mirror image, when virtual machine carries out file
During read operation, sub- mirror image is first searched, such as fruit mirror image there are data, then directly read from sub- mirror image, otherwise again from father's mirror image
Read.And when virtual machine carries out file write operation, can be written directly in sub- mirror image, during such subsequent reads, it is possible to read most
The data newly changed.In this way, all virtual machines all share the basic data of father's mirror image, in virtual machine component upgrade,
Father's mirror image can be upgraded in theory, its change can be applied in all virtual machines based on father and son's mirror, be formed
Batch upgrade.But in practical operation, many problems can be run into.
Fig. 2 is the occupancy relation schematic diagram to virtual sectors according to father and son's mirror image in correlation technique, as shown in Fig. 2 A1 is father's mirror
Picture, A2, A3 are corresponding sub- mirror image, wherein, each small lattice are represented in the corresponding virtual sectors of virtual disk, Fig. 2, father's mirror
The data of picture occupy 0-2 sectors, when A2/A3 classification mounting virtual machines, and carry out after a period of time read-write, A2 mirror image numbers
According to having newly increased 3,4,7 three sectors, and A3 mirror image datas have newly increased 5,7 two sectors.The problem of so causing
It is that when it is desirable that directly being changed A1 father's mirror image, new sector distribution will necessarily be related to, but we do not know pair
The sub- mirror image answered, which whether there is, occupies the sector, if having occupied the sector, and corresponding virtual machine is reading the sector contents
When, directly it can be read from sub- mirror image, the modification of such father's mirror image cannot be by virtual machine aware, and batch upgrade also cannot be into
Stand.
Solution in correlation technique has a variety of：1, all sub- mirror images can be scanned, analyze which virtual sectors also not
Use, can be used as the upgrading to father's mirror image, but disk read-write operation can be carried out always in operation in view of virtual machine,
Therefore this method must suspend all virtual machines, if virtual machine quantity is a lot, either close or scanning disk is all very big
Work.Meanwhile, it is the function of file system to the selection of disk sector, the realization of the function is also needed to virtual machine file system
The modification of system, therefore, the solution are difficult to implement in engineering.2, sector reservation can be carried out to father's mirror image, method can be with
It is that special identifier is carried out to its partial virtual sector making father's mirror image, forms reserve sector, and prevent virtual loom mirror image from accounting for
Corresponding sector is used, so, in upgrading, this part reserve sector can be directly used, will not be taken with virtual loom mirror image
It is overlapping.But which is still faced with the problem of needing file system in modification virtual machine, since it is desired that clearly setting upgrading
Data in magnetic disk is placed on reserve sector, and this has to be supported based on virtual machine file system.Therefore, this method is also
It is that complexity is higher.
For in correlation technique, the problem of upgrading complicated based on the virtual machine cluster that father and son's mirror image is disposed, there is presently no effectively solve
Certainly scheme.
