Red Hat RHEVS Virtualization
Red Hat RHEVS Virtualization
January 25, 2012
There are any number of different key use cases for Linux. One of the fastest growing areas is virtualization, and it's one where Linux leader Red Hat is now out with a new release.
1. Red Hat Enterprise Virtualization 3.0
Since its inception, the Red Hat Enterprise Virtualization (RHEV) product has had one key critical fault -- it required users to have Windows in order to manage a Linux virtualization system. That has now all changed in RHEV 3.0, which was officially released last week.
With the 3.0 release, RHEV is no longer based on its original Microsoft .Net roots for the management layer. Instead, it has now been re-written in Java, so Linux virtualization can be done on Linux hosts without requiring Windows.
In addition to delivering server virtualization, RHEV 3 is all about enabling Virtual desktop infrastructure (VDI). That's right Linux desktops for everyone!
2. Red Hat Opposes SOPA
SOPA, the Stop Online Piracy Act that is making its way through the U.S. Congress, dominated the tech news cycle last week. Prior to that, Red Hat had been strangely silent on its SOPA stance; now it has a position. Red Hat's legal team has taken the (correct) view that SOPA threatens innovation and economic growth.
"Measures that block the freedom and openness of the Internet also hinder innovation," Red Hat's Legal team wrote in a statement about SOPA. "That poses a threat to the future success of Red Hat and other innovative companies."
3. Linux Is Growing
The Linux Foundation published new stats last week about Linux adoption trends and future outlook. It's a future that sure looks rosy from their vantage point, with 80 percent of respondents indicating they have added Linux servers in the past year and plan to add even more in the coming year.
A key area of potential growth for Linux adoption is in the Big Data space. According to the Linux Foundation survey, 72 percent of survey respondents plan on using Linux to support Big Data efforts.
4. Linux 3.3 Testing
Linus Torvalds released the first release candidate for the upcoming Linux 3.3 kernel last week after a two-week merge window.
"And it really was a pretty busy merge window," Torvalds wrote in a mailing list posting. "I don't know *why* it felt so busy, though. In pure numbers, the merge window seems to have been pretty normal -- the number of merges and regular commits are right where you'd expect them."
In terms of the breakdown of what is in the first Linux 3.3 release candidate, it's 20 percent architecture updates, 60 percent drivers and 20 percent 'random' stuff, which includes filesystems and networking improvements.
"Anyway, it's out now, and I'm taking off early for a weekend of beer, skiing and poker (not necessarily in that order: 'don't drink and ski')," Torvalds wrote.
5. NSA Debuts Security Enhanced Android
SELinux (Security Enhanced Linux) is a key project originated by the U.S National Security Agency (NSA). It has found its way into multiple Linux distributions, most notably Red Hat Enterprise Linux as a way to provide mandatory access controls.
Now Android is getting the Security Enhanced treatment from the NSA, too.
"Security Enhanced (SE) Android is a project to identify and address critical gaps in the security of Android," the SE Android project page states. "Initially, the SE Android project is enabling the use of SELinux in Android in order to limit the damage that can be done by flawed or malicious apps and in order to enforce separation guarantees between apps."
