Virtualization's Business Value

Data center servers are notoriously under-utilized. Most servers do not come close to peak operating capacity on any given day. In fact, according to Gartner’s white paper on Data Center Power and Cooling Scenario Options for the World Ahead, April 2007 during a 24 hour period less than 10% of the typical x86 /x64 server computing capacity is used.

Server virtualization tackles this issue by abstracting the application / operating system sets from the physical systems providing for more than one set to be run on each physical system. As current systems are underutilized and difficult to reallocate based on demand, virtualization lets the IT team place more work quickly and appropriately on less physical servers – optimizing usage and minimizing the amount of physical assets to manage and support.


Tom Pisello throws some light into the ROI when virtualizing. If you don't know who tom is , just check out the software which VMware uses for TCO calculations.

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!
