Description

A kind of generation of virtual device and dispositions method
Technical field
The invention belongs to virtual computer environment technical field is and in particular to a kind of generation of virtual device and deployment side Method.
Background technology
At present, Intel Virtualization Technology is more and more extensive in the application of IT field.With multiple nucleus system in recent years, cluster, grid with And the widespread deployment of cloud computing, advantage in business application for the Intel Virtualization Technology increasingly embodies, and not only reduces IT cost, and Also enhance security of system and reliability, during virtualized concept is also gradually deep into the daily work of people and lives.
We are primarily referred to as platform virtualization technology at usually said virtualization, by using control program, hide specific The real physical characteristics of calculating platform, provide the user abstract, the unified, computing environment of simulation, and referred to as virtual machine is virtual The operating system run in machine is referred to as Client OS;The actual physical machine running virtual machine we term it main frame, The operating system running monitor of virtual machine is referred to as host operating system.
In virtual computation environmental, the exploitation of application software, distribution, the subject matter that runs into is during deployment:
(1) develop difficulty, show that development and application software must take into and take into account multiple platforms, such as Windows, Linux etc., It is also noted that the different editions of each platform, such as Windows XP, Windows7 etc..
(2) deployment trouble, the installation of application is generally difficult to avoid complex steps, and training difficulty is it is easy to occur problem.
(3) difficult in maintenance, provide an application not only to include the software of application software developer, also include operating system, Data base, middleware, developing instrument collection etc., these factors are all the maintenance of software and upgrading brings risk.
For solving the difficulty of applied software development deployment, in virtual computation environmental, it is possible to use virtual device technology.Empty Intend device, be a pre-configured software stack, including one or more virtual machines, and wherein each virtual machine can be certainly Run, and from tape operation system and related application, and its required virtual resource clear and definite.Virtual device and common virtual Machine is compared, and it all has certain advantage at the aspect such as cross-platform, the support to multi-layer framework, pre-configured and pre-optimized.Specifically Be embodied in following some:
One is that exploitation is simple.Because developer can limit operating system, the middleware data that application software is run The version of the softwares such as storehouse, such as SLES 11, WAS 7 and DB2 9.7 etc., are so effectively reduced the scope of exploitation and test, from And greatly reduce application and development and the difficulty tested and complexity.
Two is that deployment is simple.When disposing using virtual device mode, according to first installation operation system, then centre need not be installed Part, data base, the mode finally installing application software is disposed, but direct deployment becomes complete application system, can be by The original work needing several days shortens to a few minutes, original tens step operations can be simplified to a step.
Three is to safeguard simply.Because whole virtual device is from same software developer (ISV), any Software upgrading and technical support, as long as all He one ISV contact is just permissible, simplify related procedure.
Open virtual machine form (OVF, Open Virtualization Format) is promoted to the demand of virtual device Birth.Publisher's distributed task management group (DMTF, Distributed Management Task Force) of OVF is One non-profit-making industry member cooperative association.The design concept major embodiment of OVF this six aspects below:
(1) it is conveniently distributed:Support the safety measures such as certification and the integrity check of virtual device, and software license is provided Administrative mechanism;
(2) multiple frameworks are supported:Including single virtual machine, multiple virtual machine or multilamellar (Multi-Tier) framework;
(3) cross-platform:OVF agreement does not rely on specific virtual platform, such as VMware or Xen;
(4) open protocol:OVF agreement is the product of cooperation between several big virtualization technology suppliers of industry, and encourages More enterprises participate;
(5) expansible:OVF agreement can not only meet existing requirement, and constantly sends out to meet virtual device technology Exhibition and some special needs, it also supports a certain degree of extension;
(6) support localization:The user that those non-English speaking countries can be helped advantageously is used by this.
Following some master files are comprised in one OVF bag:
(1) OVF describes file:Commonly referred to " OVF envelope ", it is an XML document, for defining whole virtual device Ingredient (such as virtual machine), and the characteristic of each ingredient and resource requirement, suffix entitled " .ovf ";
(2) virtual disk files:The i.e. binary system disk mirroring of virtual machine;
(3) inventory file:Inventory comprises SHA-1 summary (also referred to as " verification and ") of each file in OVF bag, and its effect is true The integrity of Bao Bao, suffix entitled " .mf ";
(4) certificate file:Effect is to guarantee the credible of whole virtual device by being digitally signed to inventory file Property, with the X.509 certificate form storage of base64 coding, suffix entitled " .cert ";
(5) OVF environment (Environment) file:The XML document of one key assignments (Key-Value) form, for setting With the configuration safeguarding software on virtual machine, suffix entitled " .env ".
Existing virtual device is a complete application system in itself, has been completed installation and the configuration of software.? A small amount of operating system basic configuration can only be changed, such as IP address, CPU number etc. during deployment.Virtual device technology exists at present It is used widely in business software, such as VMware, the company such as IBM, Oracle is all the application software of oneself with virtual device Form issue.User by network download virtual device, be deployed in virtual computation environmental, start virtual machine so that it may so that With corresponding software it is not necessary to consider physical machine, operating system, run the software and hardware compatibling problems such as lab environment it is not required that entering The installation configuration of row software.
Virtual device comprises to run the full content of virtual machine, including operating system, data base, middleware and application in itself Software etc..But at present, the requirement to hard drive space for the operating system constantly becomes big, in the case that such as Windows XP typical case installs Need hundreds of MB, Windows7 needs about 5~6GB, acceptance of the bid kylin (SuSE) Linux OS needs about 2~3G.Relatively and Speech, the volume of application software is much smaller, typically not greater than 100MB.Many times, the void that different information systeies is used Intend device, the operating system being used is identical (being all such as Windows 2003), different is application software part. In this case, if issuing multiple virtual devices, then actually, under identical basic operating system file is repeated Send out repeatedly.When issuing using network transmission mode, the network bandwidth can be caused to repeat to take the prolongation of data transmission time;? When issuing using CD or portable hard drive mode, hard-disk capacity can be caused waste.
Therefore, need a kind of dispositions method based on virtual device of development badly, for deployment information in virtual computation environmental The demand of system, solves device file in existing commercialization virtual device technology excessive, to the transmission bandwidth larger, transmission time of requirement Longer, and the problem that hard-disk capacity wastes.
