Virtual Appliances will tilt OS dynamic!

Microsoft and other OS vendors have definite reasons to worry. When you get into the "Virtual Appliance" mindset, you just think of the app, you don't even want to (or must I say have to) touch the OS. There is a big chance that Linux will gain popularity with its simpler, thinner images BUT be warned Microsoft too is going strong with its console based OS.

In order for a virtual machine to run, users need to have a virtual server in place, explained Gary Chen, enterprise research, SME IT infrastructure and applications senior analyst at the Yankee Group. He is author of the new Yankee Group report, "Virtually Possible: Virtual Appliances Ready to Shake Up Application Delivery."

Enterprises may use virtual servers from Xen, VMware and even Microsoft's new Hyper-V. All of them support a standard called OVF (Open Virtual Machine Format), Chen said.

In a world of virtual machine-delivered software, open source OSes, such as Linux, may gain greater use, because of the integration advantages for ISVs.

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!
