Red Hat integrated Xen virtualization solution

Article Title: Red Hat integrated Xen virtualization solution details. 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.

HOST: The Impact of virtualization technology on the Linux world is not the same for all operating systems. Why?

Jin Lin steel: it should not be said that the impact.

HOST: many comments have said that virtualization technology in Linux has brought new hopes to them?

Jin Lingang: Linux is very mature and widely used. Why are so many people concerned about this technology? Because Linux can reach any corner. With Linux, the cost is very low. How can we make better use of existing resources and reduce the cost? The virtualization environment can help them achieve this. In the past, we saw reports from IDCs that CIOs are concerned about how to increase their revenue and how to quickly launch new services? We think, for example, how can we launch higher incomes? A better solution for continuous product innovation is open source. Open source is something that millions and tens of millions of people around the world are working together to make technological innovation easy. How can we push new services? It is virtualization technology, because a machine is equipped with a digital machine to deploy this item and it can be launched immediately, which is faster than usual and does not need to increase costs.

HOST: What are the details of the solution provided by RedHat? What does this solution look like? What are the components of this architecture?

Jinlin steel: Red Hat is an integrated virtualization environment. Virtualization is only part of it. Don't say that virtualization is actually used with Xen and can be used very well. I have already discussed how to virtualize the file system. How can I make full use of sharing when I run five or six operating systems and applications on one machine? Or are resources fully shared? We propose a concept named red hat with a GFFS global file system. In this way, each operating system can share its data. This has one advantage: Once a system load is too heavy on this physical machine, I can let users feel nothing to migrate this system to another system. It is because of the virtualization technology that can be achieved, so that the system can quickly respond to customer needs.

HOST: As far as I know, is there a storage virtual? Even a file system?

Jin Lin steel: Yes. In addition, since a system is virtualized to run an application, in some cases, for example, a network server, for example, a network server, is provided to hundreds of users, hundreds of service lines can be opened on one machine. Many engineers are required for manual installation. Red Hat puts forward a concept that makes full use of the Red Hat Network Function to configure everything in advance and put it on the Red Hat Network. when you need it, you can deploy the entire image in just a few minutes.
