Information related to the Virtualization in Linux Kernel

Users of Vista Business, Linux kernel development can be very complex and mysterious, as maintained by the dozens of different parts, there are hundreds of volunteers to submit code, it's difficult to judge the trend of new features. In essence, the development of Linux there is no road map. To get a glimpse of the whole picture, the following is worth noting the but the development, based on the kernel developers and maintenance personnel interview. So I need to know the Information related to the Virtualization in Linux Kernel

Recognizing that, in this decade, virtualizations increasingly becoming a "trend", Linux kernel maintainer it as a priority function, accelerated virtualization technology added to the kernel process. By the start-up Qumranet's KVM virtual Avi Kivity provides management procedures contained in the late 2006 release of the kernel and in the last month's release continue to escalate.

I believe that the KVM is not suitable for business use." He added, in the KVM can be added to the SUSE Linux before; it needs to include the scheduler in the kernel subsystem interactions on the go through more tests. Citrix Systems recently acquired to spend five million dollars of commercial open source virtualization company XenSource, has been trying to persuade its own structure Xen virtual machine hypervisor (Hypervisor) added to the kernel inside.

According to me Core maintenance personnel to add this virtualization capabilities that will greatly increase the maintenance workload. XenSource engineers finally gave up, but still continue to adjust to cope with the kernel running Xen. It is temporarily not enter the kernel, only the first adds some support to run a virtual Linux environment it can be identified.

Other rapid development of virtualization capabilities, including KVM and Lguest. Lguest by IBM engineers developed a Rusty Russell is only 5000 lines of code to streamline the hypervisor (virtual machine management program), which is already included in recent versions of the kernel inside the. And KVM similar, which supports the latest Intel and AMD chips, virtualization technology.

With VMware's ESX Server is different from the Lguest created a virtual machine inside a virtual operating system know they are out. Therefore, CPU cycles when it is called directly to the real hardware can be a request, rather than as an intermediary to lower efficiency, so this architecture greatly improved efficiency.
