Virtualization in a nutshell



Martin (of IBM) explains:

The overall management of the IT infrastructure is also simplified because virtualization decouples consumers and resources. Therefore, the consumer is not dependent on the specific implementation of the resource. With this decoupling, administrators can manage the IT infrastructure while mitigating any effects of management actions on the consumers. Management actions can be accomplished manually, semi-automatically, or automatically driven by service-level agreements (SLAs).

In its foundation, grid computing makes wide use of virtualization. Grid computing virtualizes the IT infrastructure. It deals with sharing and managing the IT infrastructure to dynamically provision the resources that meet user and application requirements, while providing simplified access to the infrastructure.


It is crucial to view and treat virtualization as a commodity and not blow it out of proportions. Virtualization will eventually take the IT to where it belongs. Out of our hands! No more manual operations, just like your electricity grid. It just flows! It ought to, right?

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!
