Description
Technical field
The invention belongs to virtual computer environment technical fields, and in particular to a kind of generation and deployment for simplifying virtual device
Method.
Background technique
Currently, virtualization technology is in IT field using more and more extensive.With multiple nucleus system, cluster, grid in recent years with
And the widespread deployment of cloud computing, advantage of the virtualization technology in business application increasingly embody, and not only reduce IT cost, and
And security of system and reliability are also enhanced, the concept of virtualization is also gradually deep into people daily work and life.
We are primarily referred to as platform virtualization technology at usually said virtualization, by using control program, hide specific
The real physical characteristics of computing platform provide abstract, unified, simulation calculating environment, referred to as virtual machine for user, virtually
The operating system run in machine is referred to as Client OS；The actual physical machine of virtual machine is run we term it host,
The operating system of operation monitor of virtual machine is referred to as host operating system.
In virtual computation environmental, the main problem that exploitation, distribution, the deployment of application software encounter in the process is：
（1）Exploitation is difficult, shows that development and application software must be taken into consideration and takes into account multiple platforms, such as Windows, Linux, also
It is noted that the different editions of each platform, such as Windows XP, Windows7.
（2）Deployment trouble, the installation of application are generally difficult to avoid complex steps, and training is difficult, it is easy to problem occur.
（3）It is difficult in maintenance, provide one application not only include application software developer software, further include operating system,
Database, middleware, developing instrument collection etc., these factors are all that the maintenance and upgrade of software brings risk.
Virtual device technology can be used in virtual computation environmental to solve the difficulty of applied software development deployment.It is empty
Quasi- device is the software stack of a pre-configuration, including one or more virtual machines, and wherein each virtual machine can be certainly
Operation, and from tape operation system and relevant application, and clear virtual resource needed for it.Virtual device and commonly virtual
Machine is compared, it the cross-platform, support to multi-layer framework, pre-configuration and in terms of all have certain advantage.Specifically
It is embodied in the following：
First is that exploitation is simple.Because developer can limit operating system, middleware and the database etc. that application software is run
The version of software, such as SLES11, WAS7 and DB29.7 etc., in this way by effective range for reducing exploitation and test, thus pole
The earth reduces the difficulty and complexity of application and development and test.
Second is that deployment is simple.When disposing using virtual device mode, without according to first installing operating system, then centre is installed
Part, database, the mode for finally installing application software are disposed, but directly deployment becomes complete application system, can be incited somebody to action
Originally it needed work in several days to shorten to a few minutes, and original tens step can be operated and be simplified to a step.
Third is that maintenance is simple.Because entire virtual device is from the same software developer（ISV）, so any
Software upgrading and technical support simplify related procedure as long as all contacting with an ISV.To virtual device
Demand promotes open virtual machine format（OVF, Open Virtualization Format）Birth.The publisher of OVF point
Cloth task management group（DMTF,Distributed Management Task Force）A non-profit-making industry at
Member cooperative association.The design concept major embodiment of OVF is below in terms of this six：（1）It is conveniently distributed：Support virtual device
Certification and the safety measures such as integrity check, and provide the administrative mechanism of software license；
（2）Support a variety of frameworks：Including single virtual machine, multiple virtual machines or multilayer（Multi-Tier）Framework；
（3）It is cross-platform：OVF agreement is independent of specific virtual platform, such as VMware or Xen；
(4）Open protocol：OVF agreement is the product cooperated between industry Ji great virtualization technology supplier, and is encouraged more
More enterprises participate；
（5）It is expansible：OVF agreement is not only able to satisfy existing requirement, but also continues to develop to meet virtual device technology
With certain special needs, it also supports a degree of extension；
（6）Support localization：This will help the user of those non-English speaking countries advantageously to use.
It include following some master files in one OVF packet：
（1）OVF describes file：Commonly referred to as " OVF envelope " is an XML document, for defining entire virtual device
Component part（Such as virtual machine）And the characteristic and resource requirement of each component part, suffix are entitled " .ovf "；
（2）Virtual disk files：That is the binary system disk mirroring of virtual machine；
（3）Inventory file：Inventory includes the SHA-1 abstract of each file in OVF packet（Also referred to as " verification and "）, effect
It is to ensure that the integrality of packet, suffix is entitled " .mf "；
（4）Certificate file：Effect be by being digitally signed the credibility to ensure entire virtual device to inventory file,
With the X.509 certificate form storage of base64 coding, suffix is entitled " .cert "；
（5）OVF environment（Environment）File：One key assignments（Key-Value）The XML document of form, for setting
With the configuration of software on maintenance virtual machine, suffix is entitled " .env ".
Existing virtual device itself is a complete application system, has been completed the installation and configuration of software.?
A small amount of operating system basic configuration can only be modified when deployment, such as the address IP, CPU number etc..Virtual device technology has been at present
It is used widely in business software, such as VMware, the companies such as IBM, Oracle are all the application software of oneself with virtual
The form of device is issued.User downloads virtual device by network, is deployed in virtual computation environmental, starts virtual machine, so that it may
To use corresponding software, without the concern for physical machine, operating system, the software and hardwares compatibling problem such as operation lab environment is also not required to
Carry out the installation configuration of software.
Virtual device itself includes the full content for running virtual machine, including operating system, database, middleware and application
Software etc..But currently, requirement of the operating system to hard drive space constantly becomes larger, such as the case where WindowsXP typical case's installation
It is lower that several hundred MB, Windows7 is needed to need about 5~6GB, kylin Linux operating system of getting the bid needs about 2~
3G.In contrast, the volume of application software is much smaller, typically not greater than 100MB.Many times, different information systems
Used virtual device, used operating system are identical（It for example is all Windows2003）, different only answers
Use software section.In this case, if issuing multiple virtual devices, actually, identical basic operating system
File, which is repeated, have been issued repeatedly.When being issued using network transmission mode, it will cause network bandwidth and repeat to occupy and data biography
The defeated time extends；When issuing using CD or mobile hard disk mode, hard-disk capacity can be caused to waste.
Therefore, it needs to develop a kind of dispositions method based on virtual device, for the deployment information in virtual computation environmental
The demand of system, solves in existing commercial virtual device technology that device file is excessive, requires larger, transmission time to transmission bandwidth
The problem of longer and hard-disk capacity wastes.
