Linux Virtualization: Kernel 2.6.20 and KVM performance



I guess getting the Big Blue into the game (they have always helped the OSS out , look at Eclipse) might help KVM get really ahead of others in terms of performance. Also I guess by the time of oficial release of the kernel, the tests will show a lot more but for the time being, as this author says:

Looking over the virtualization performance results, KVM was not the clear winner in all of the benchmarks. KVM had taken the lead during Gzip compression, but in the other four benchmarks it had stumbled behind Xen 3.0.3. However, both Xen with full virtualization and the Kernel-based Virtual Machine had performed in front of QEMU with the QEMU accelerator in our select benchmarks using dual Intel Xeon LV processors with Intel Virtualization Technology. The benefits of KVM are high performance, stable, no modifications of the guest operating system are necessary, and a great deal of other capabilities (e.g. using the Linux scheduler). Once the Linux 2.6.20 kernel is officially out the door we will proceed with a greater number of KVM benchmarks in various environments including looking at the hardware virtualization performance between AMD and Intel.


I am rather curious. Read the article here from Phoronix.

Avastu Blog is migrating to IdeationCloud.com; 1st Jan 2009 live

YOU DON'T HAVE TO DO ANYTHING. WITHIN 2 SECONDS YOU WILL BE REDIRECTED TO THE NEW HOME OF AVASTU BLOG. PLEASE DO UPDATE AVASTU BLOG'S URL to : http://www.ideationcloud.com on your website.

I will send out emails personally to those who are using my link(s) on their sites.

Thanks much for your co-operation and hope you enjoy the new site and its cool new features :-)




Not like the site is unlive or something..on the contrary, its beginning to get a lot of attention already. Well most of the work is done, you don't have to worry about anything though:

What won't change

Links/Referrals: I will be redirecting the links (all links which you may have cross-posted) to IdeationCloud.com - so you don't have to do anything in all your posts and links. Although, I would urge however that you do change the permalinks, especially on your blogs etc yourselfThis blog is not going away anywhere but within a few months, I will consider discontinuing its usage.

Cloud Security: Eliminate humans from the "Information Supply Chain on the Web"

My upcoming article, part - 3 data center predictions for 2009, has a slideshot talking about the transition from the current age to the cloud computing age to eventually the ideation age- the age where you will have clouds that will emote but they will have no internal employees.

Biggest management disasters occur because internal folks are making a mess of the playground.

Om's blog is carrying an article about Cloud security and it is rather direct but also makes a lot of sense:

I don’t believe that clouds themselves will cause the security breaches and data theft they anticipate; in many ways, clouds will result in better security. Here’s why: Fewer humans –Most computer breaches are the result of human error; only 20-40 percent stem from technical malfunctions. Cloud operators that want to be profitable take humans out of the loop whenever possible.Better tools – Clouds can afford high-end data protection and security monitoring tools, as well as the experts to run them. I trust…
