(InfoWorld) - Hewlett-Packard is upgrading its virtualization software offerings to help data center managers better manage their virtual environments, while VMware is offering a virtualization capability for Web hosting companies. HP on Wednesday announced enhancements to its HP Virtual Server Environment software for its Integrity line of servers, which creates a pool of virtual servers that can expand and contract depending on capacity needs. Virtualization refers to the practice of running multiple software applications on one physical server to enhance utilization. Previously, most servers were dedicated to running only one application, but that kept utilization rates as low as 15 to 20 percent. Virtualization increases server utilization, thus reducing the need to buy, power, cool, and manage additional servers. HP also offers a specific software tool, Integrity Essentials Capacity Advisor, for easing the migration of data from Sun servers to HP servers. Although virtualization improves server utilization, it requires different management tools than a nonvirtual environment. HP says the Integrity Essentials Global Workload Manager, another feature of Virtual Server Environment, specifies which computer workloads can automatically access available capacity in order to maintain service level agreements for key applications. The company also announced a new Partner Virtualization Program, which allows ISVs to test how their software will work in an HP virtualization environment. Testing and fine-tuning can be done for virtualization using HP ProLiant and Integrity servers and with a number of operating systems, including HP-Unix, Windows Microsoft, and Novell and Red Hat Linux. The Virtual Server Environment also works with VMware virtualization software. Meanwhile, VMware announced Wednesday the launch of its VMware Service Provider Program, which allows Web hosting services, telecommunications companies, and other outsourcing businesses to include virtual infrastructure as a service offering. Traditional hosting services use dedicated servers for each client, but virtualization makes it possible to run multiple virtual servers, even for different clients, on one physical server. The Web hosting company can then bill clients monthly based on how many virtual machines they use, not physical ones, VMware said.

Security researchers have uncovered "critical" security flaws in a version of the Linux kernel used by a large number of popular distributions.The three bugs allow unauthorized users to read or write to kernel memory locations or to access certain resources in certain servers, according to a SecurityFocus advisory.They could be exploited by malicious, local users to cause denial of service attacks, disclose potentially sensitive information, or gain "root" privileges, according to security experts.The bug affects all versions of the Linux kernel up to version 2.6.24.1, which contains a patch. Distributions such as Ubuntu, Turbolinux, SuSE, Red Hat, Mandriva, Debian and others are affected.The problems are within three functions in the system call fs/splice.c, according to an advisory from Secunia."In the 2.6.23 kernel, the system call functionality has been further extended resulting in ... critical vulnerabilities," said iSEC Security Research in an advisory.Secunia disagreed about the bugs' seriousness, giving them a less critical ranking.Exploit code for the vulnerabilities has been released publicly on the hacker site milw0rm.com, and Core Security Technologies has also developed a commercial exploit for the bugs, researchers said.Researchers advised system administrators to update their kernels immediately.Last month, a U.S. Department of Homeland Security bug-fixing scheme uncovered an average of one security glitch per 1,000 lines of code in 180 widely used open-source software projects.Secunia also previously discovered that the number of security bugs in open-source Red Hat Linux operating system and Firefox browsers, far outstripped comparable products from Microsoft last year.
