Rosenblum: We're better than Microsoft

Q&As:

InformationWeek: VMware put ESX Server on a weight loss plan to get it down from two gigabytes to 32 megabytes in the just announced, embeddable, 3i version. How did you do that?

Rosenblum: We've typically included a version of Red Hat Linux in ESX Server. That's because the hardware manufacturers put little embedded processors to control the fans and other elements of their servers. They have agents reporting on their operation. They wouldn't write software that would allow those processors to interface to ESX Server, but they had to do it for Linux. So we shipped a full Red Hat operating system as our management console.

InformationWeek: And since you're embedding ESX Server in the hardware, you could throw out the console?

Rosenblum: Yes, now we're in a much better position. The footprint is smaller, the security exposure is smaller, we don't have to patch for security issues. We get rid of two gigabytes of code. You no longer have to wait for Linux to boot up. It [ESX Server 3i] starts relatively fast.

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!
