Virtual machine is the industry's hot, but its situation has spread out of control trend. Why virtual machines is growing so quickly? Is simple: "a machine using an operating system" rule is now outdated, the virtual machine software so companies can make all the CPU capacity to expand use of hardware resources.
However, all the virtual machine software needs to be managed. So we only need to solve the problem 5, in order to implement the program in a large, virtual machine management into a practical approach.
1. Multiple versions of the virtual machine image to a snapshot of how to deal with tracking?
Image (including the virtual machine guest operating system of the state) must be based on a snapshot of their network location tracking, a snapshot of how to use these images, and their repair and patch status for what.
Usually on the use of virtual machine technology is client operating system (with applications) package to ISO file or other image file can be installed, these ISO files or image files can then be used as a virtual client to a server installation.
Ensure that the image file contains the sub module and patch and repair the file, there are revised to keep pace with each other, and update policies to keep pace with the company, these are essential.
2. How to migrate virtual machines to increase and change management?
Virtualization technology means that the host, the guest operating system and applications running on their mobility. As to create a virtual machine operating system to allow many clients can reside on one host, move, add or change will affect the client operating system or application instance.
To keep track of the status of these changes is necessary, as the host or neighboring use of customer resources and performance tracking.
Although each virtual machine supplier performance tracking, and maintain control of positioning and performance statistics, and the volatile combination of guest operating systems and applications with heterogeneous client host or Administrator on the client system will the application and the operating conditions of the approval process challenges.
3. How to regulate virtual machines and application of the subsidiary system?
One of the advantages of virtual machine environment is the flexibility, the virtual machine to support an application from a mainframe hardware platform to be moved to another platform.
In order to facilitate such migration, IT managers must understand the process required in the relevant instance of migration and Sub-system synchronization, the application is effective. An example of these ancillary systems may be facing the world of network hosts, such hosts need to have on the ability of the background database accessible; migrate a host, domain name server, routing, and / or authentication settings may need to be modified.
4. Users and administrators how to cross virtual machine management?
As the virtual machine guest operating system and application specific hardware environment from separate, the image file consistency and security authentication is very important.
Create a virtual machine from the elements to change the configuration, adjust parameters and the use of virtual machine infrastructure in the whole process, the implementation of management control are very necessary. Virtual machines can easily migrate from one host to another quick virtual host.
To prevent unauthorized use of the image file, you must modify the configuration using the system configuration audit and review of control methods.
Most enterprises to adopt hierarchical management strategy, hardware, virtual machine, guest operating system and run the application server to implement various levels of management control. These different types of access must be managed, and must have put in place audit systems to track all actions.
5. To determine a reason for the virtual machine stops running, figuring out what methods can be used?
Whenever a virtual machine, guest operating system or resides on a virtual machine running on an application exception, the IT staff is not only to understand the events, and understand the conditions leading to abnormal operation of the identification information is also occurring very important.
Location, setting, client operating system and application behavior, and other features, to identify and support for decisions, and control and audit purposes for the help desk to provide quality information feedback loops, all play a very important role.
With the public security authorities to find or clean-up "One" user 9000 households times, real-name registration of 48 961 "One" user information. In the mobile voice (mobile IVR) information service governance, and further issued a document defined by China Mobile and China Unicom to change business as the main responsibilities, the two operators to review and strengthen the things in the allocation of prior efforts to test the mobile IVR business mass induced check the effectiveness of text messaging more obvious problems. Statistics show that the complaint rate of telecommunications users in general show a clear downward trend, such as Jiangsu Province, 12,300 complaints over the messages down 53.75% over the same period last year, Guangdong Mobile adverse information received complaints from users fell 80%. Ministry of Information Industry website registration system is upgraded, the Congress party's 17 officially put into trial operation prior to the relevant authorities opened the Internet to provide information queries. This will improve the cooperative investigation of the efficiency of illegal sites make Internet-based systems support the ability of management to further improve.
