XEN enables a computer to run multiple operating systems, enabling your computer to complete as much task as possible. At present, this technology is very common in the high-end server field, but on the mainstream system, this feature needs to be developed by EMC's VMware development.
At the LinuxWorld exhibition, many vendors expressed their support for Xen in terms of recognition, programming help, contributing code, including Sun, HP, Novell, Intel, IBM, Voltaire.
Chris, vice president of Novell's SUSE, said, 2, 3 months ago, it has not yet caused anyone's attention. It will give people a huge change in the way of using Linux.
This change indicates what project can develop well in the open source world: can promote multiple interest entities. As Linux, as long as you don't have any problems, cooperation can lead to unity, develop rapid projects, rather than exclusive, and not compatible competitors. Illuminata analyst Haf said that the open source industry ultimately decided to eliminate disagreement and support a virtualization project.
The founder of Xensource, the head of the person in charge, said Xen was born in the Cambridge University in the UK three years ago. Xen and other methods of dividing a computer into multiple different partitions depends on a concept called virtualization, which enables the software to run on hardware utilizing software simulation. In VMware, this basic concept is called a virtual machine.
VMware and Xen are: The former completely simulates a computer, theoretically, it can run any operating system without modification; Xen uses technology known as "Paravirtualization", Pratt said it is more High, but you need to make appropriate modifications to the operating system. This technique does not require modification of other high-level software.
Pratt said that the requirements for modifying the operating system will be resolved with Intel to launch VanderPool technology in 2005. This means that the unmodified operating system can also run on Xen, although slower speed. This also means that Windows will be able to run on Xen.
Xen's martyr
The competitors who do not attract eyeballs include PLEX86 and user mode Linux. Although the latter has been stationed in SUSE Linux, it seems that it will not last. Chris said that user mode Linux may have been finished.
SUSE Linux's general manager Ricks said Novell's management tool developed for user mode Linux will be used to control Xen.xen will be integrated into the Novell's upcoming SUSE Linux Professional 9.3, and then integrated into the new version. SUSE Linux Enterprise Server.
Red Hat also developed a Xen program. Red Hat is responsible for the implementation of the executive vice president Paul, said Xen is being integrated into Fedora Core 4, which may also be integrated into the Red Hat Enterprise Linux 5. Like Novell, Red Hat also develops control to add or delete the management tool for Xen virtual machines.
Hewlett-Packard said last week to contribute to Xen, expressed its support for Xen. When you speak on the LinuxWorld Exhibition, HP is responsible for Linux vice president Martin, saying that Xen will be able to provide a viable open source virtual platform. HP also hopes to benefit from the software that manages virtual computer.
The Bunder of Intel Digital Enterprise Group said that they start to contribute to the Xen project from January so that it can use VanderPool technology.
Expand Xen's territory
Currently, Xen runs on the Linux-x86 platform. Last week, AMD announced that it is helping to transplant Xen to its current and future versions of the Opteron chip. Lalat said that it is still conducting Tests of Xen on the Anteng chip. Chris said that IBM has expressed its interest in porting Xen to the Power chip. Pratt said NetBSD has been able to run on Xen. John, Executive Vice President, Executive Vice President, said that Solaris may be another support system that supports Xen. He said that we think that open source virtual software is a direction.
IBM will play an important role in the Xen project
People who understand the IBM program are expected to play an important role in the Xen project. It has experience in developing large hosts, UNIX servers, and Intel chip servers. Although the sales and development cooperation agreement is signed with VMware, the IBM is also conducting a virtual technology project for X86 chips.
IBM researchers are using it as a foundation called "Secure Hypervisor", the "Secure Hypervisor" project is designed to ensure that the virtual computer will not be attacked. IBM researchers Sele said that we now plan to contribute the project to Xen. Pratt gave a positive comment on this. He said that IBM can contribute a safety frame for Xen.
IBM's plan is more than this. According to informed sources, IBM also plans to contribute two key computing technology software ━ Equipment communication I / O services, using hard disk to expand the virtual memory of memory.
Although Xen supported Xen, IBM reaffirmed the relationship with VMware last Thursday. IBM's spokesman Jim said that we have a strong and important business relationship with VMware, and our close relationship has reached an unprecedented level.
VMware called Xen as a "newborn" virtualization project, requiring the modification of the operating system to affect its development. VMware said in a statement that Xen is not very useful for companies that deploy standard Linux operating systems.
But Haf said, VMware, Intel's VT, Microsoft's Virtual Server will face challenges. Although VMware has a higher level of VirtualCenter and VMotion software, the core virtualized products are critical to it. Hav, said most of its income comes from here.
