User-mode Linux Linux operating system allows other operating systems running in user space. Linux operating system for each customer present in the host Linux operating system, a process. This allows the Linux kernel to run a single Linux kernel. Figure 6. User-mode Linux in the Linux version of the Linux 2.6 kernel, UML resides in the main kernel tree, but it must be ahead of schedule, and then recompile to use. These changes in addition to the common virtualization capabilities, it can also provide equipment virtualization. As a result, guest operating systems can share the available physical devices, such as block devices, consoles, NIC device, sound hardware. Note that the client kernel is running in the application space, so they must be special for this usage compiled. This produced a host kernel and client kernel. These kernels can even be nested, allowing a customer kernel in another client running on the host kernel to run on the kernel. "We still have a lot of different products, such as optical storage, the S1500 from the low-end for many small and medium enterprises, in the end of the S2500, and to compare the high-end market in China, the S2900, to adapt to the needs of large storage product line." Xi Li said.
Raikes said Microsoft business division president, to take the current market and future market comparison is wrong. Appears in Lycos, Googles challenge to reasonable under the misguided attack against Microsoft, and is arrogant. Google concerned about their own interests, it is to undermine Microsoft, rather than to meet customer needs. Lycos noted that Microsoft in product development and customer research, and spent several years invested billions of dollars, carefully studied the use of employees and business software. Indeed, Microsofts advantage lies in its office software market in the huge lead. Industry analysts say, Google Desktop can not be in direct confrontation with Microsoft software. Desktop software is the software transition to the Web. Analysts pointed out that over the recent years of other rivals Microsoft, Google is a completely different competitors: its bigger, faster development, financial strength, the talent attractive. Google "cloud computing" technology is open. Their own design engineers from the Google data center energy efficiency, speed, cost very edge, so that it can add very low cost computing power.
