IBM rethinks Unix Virtualization with Unix VMotion!

Part of IBM's jump into live migration can be attributed to its acquisition of Meiosys in 2005, a start-up which had captured application live migration capabilities in its software. In some cases, IBM now allows start-ups like Meiosys to pioneer and prove technologies that it used to develop in its own labs.

In addition to moving running applications around, IBM can move a logical partition -- its version of an independent virtual machine -- around as well. Such a unit represents a combination of an application and operating system, plus the memory, storage and networking parameters with which it needs to run. Either the application by itself or the entire logical partition may be moved from one physical machine to another without disrupting end users.

The capability puts a new management tool into the hands of data center operations. Instead of taking systems down at 2 a.m. on Sunday, they can be idled for maintenance and upgrade "at 2 p.m. on Tuesday," or any other time during the regular work week, said Handy. As the work day winds down and workloads diminish, applications running on ten servers might be shifted to one to save power and cooling, he added.

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!
