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.

Security: VMware Workstation 6 vulnerability

vulnerable software: VMware Workstation 6.0 for Windows, possible some other VMware products as well type of vulnerability: DoS, potential privilege escalation I found a vulnerability in VMware Workstation 6.0 which allows an unprivileged user in the host OS to crash the system and potentially run arbitrary code with kernel privileges. The issue is in the vmstor-60 driver, which is supposed to mount VMware images within the host OS. When sending the IOCTL code FsSetVoleInformation with subcode FsSetFileInformation with a large buffer and underreporting its size to at max 1024 bytes, it will underrun and potentially execute arbitrary code.

Splunk that!

Saw this advert on Slashdot and went on to look for it and found the tour pretty neat to look at. Check out the demo too! So why would I need it? WHY NOT? I'd say. As an organization grows , new services, new data comes by, new logs start accumulating on the servers and it becomes increasingly difficult to look at all those logs, leave alone that you'd have time to read them and who cares about analysis as the time to look for those log files already makes your day, isn't it? Well a solution like this is a cool option to have your sysadmins/operators look at ONE PLACE and thus you don't have your administrators lurking around in your physical servers and *accidentally* messing up things there. Go ahead and give it a shot by downloading it and testing it. I'll give it a shot myself! Ok so I went ahead and installed it. Do this... [root@tarrydev Software]# ./splunk-Server-1.0.1-linux-installer.bin to install and this (if you screw up) [root@tarrydev Software]# /op

Virtualization is hot and sexy!

If this does not convince you to virtualize, believe me, nothing will :-) As you will hear these gorgeous women mention VMware, Akkori, Pano Logic, Microsoft and VKernel. They forgot to mention rackspace ;-) virtualization girl video I'm convinced, aren't you? Check out their site as well!
