Welcome to LinuxWorld with open-source Virtual Technology Xen

Article Title: open-source Virtual Technology Xen is welcomed in LinuxWorld. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
At the virtualization opening conference at the LinuxWorld Conference, people were very vocal. Virtualization is attractive to open-source enthusiasts and Windows Servers users.
　　
The forthcoming open-source Xen virtual machine technology (which allows multiple operating systems to run concurrently on the same physical server) version 3.0 is coming to an end. Red Hat and Novell, the main Linux publishers, plan to use Xen in their latest operating systems. At the same time, Intel will launch new chip technologies to support Xen by the end of this year. AMD also said it will make great strides next year.
　　
Simon Crosby, a founder of XenSource in Palo Alto, Calif., said some Linux users who have participated in earlier versions of Xen testing, including some senior financial institutions, have long been coveted by new Xen technologies, they plan to sell products in Xen support.
　　
But that doesn't mean they want to deploy Xen in a production environment. Timothy Golden, Senior Deputy Director of the Linux project at Bank of America, said the company is considering many ways including Xen to achieve Linux virtualization, at the same time, I am eager to see which of the earlier beta versions are useful to them.
　　
He said: "obviously we are very excited and excited. But in this regard, the most important thing is that before we release our products, the industry has sent a signal that companies are already ready to welcome new products ."
　　
　　 An exciting game
　　
A cio from an important financial company that asked for anonymity said he would not consider using Xen products until the first half of next year. "Most people share the same idea, that is, waiting for Xen to be fully integrated into Linux," he said. At the same time, we play some serious games ."
　　
His company is already using VMware commercial virtualization technology for Citrix System-based Windows terminal servers, the company's development and quality assurance machines.
　　
Among thousands of Linux servers in many financial companies, only 25-30% are applied and can benefit from virtualization. But the CIO said many users are reluctant to spend more on big Environment Virtual software.
　　
"We have many ambitious plans for Linux virtualization, and we want it to be as fast as others," he said. If we can get it today, we can deploy it. But it is not ready yet ."
　　
Not every Linux user is happy to wait for the choice of open source code to become a reality. Some IT stores have virtualized their Linux environment, and the most typical application is to use VMware software in combination with Windows servers.
　　
Ryan Pearson, a system boot administrator at WoodBury, Minnesota, said Assurant's purchase of VMware software was a strategic decision to consolidate its Windows and Linux servers. Assurant has benefited a lot, for example, reducing the number of days required to provide servers to an hour.
　　
Pearson said that Xen looks promising. If Xen is able to have the same performance as VMware's software, his company may consider Xen.
　　
Tony Adams, a technical analyst for agricultural enterprises in Boise, Nevada, said that about three years ago, J. r. the data center of Simplot has no space for any machines. They use VMware software to virtualize their Windows and Linux environments.
　　
Adams said the company was able to cut hardware by around, and now they are using VMware software on 15 physical servers, it runs 150 Windows "customer" operating systems and 50 Linux instances.
　　
David Trainor, Senior middleware analyst at Yum Brands (KFC, Pizza Hut, Taco Bell, and other fast food carriers) in Louisville, northern Kentucky, said the company may insist on using VMware. Trainor says Yum is already using it for trade, saving $250,000 in the first year.
　　
Trainor says some Windows servers in the company only occupy 1-2% of their processing capabilities. He added that Yum hopes to have 276 virtual machines on 60 machines by the end of the year.
　　
Tony Iams, an analyst at Ideas International, points out that by now, among the many server flooding problems, virtual software can help reduce the number of servers for Windows is the most significant. He also said that it is unclear whether or not Linux servers will also encounter problems that cannot be fully used.
