Overcoming virtualization drawbacks

Richard Muirhead writes about it:

Today’s virtualized data center environment is like an F15 airplane, wonderfully flexible but at the same time dangerously unstable if not managed properly. The F15 is widely recognized as one of the most maneuverable fighter jets ever built. But flexibility comes at a price and the only way you can control it is by having very good computer systems supporting the pilot flying the plane.

Similarly, the challenge of complexity is ever present in today’s IT environments and the drive towards virtualization is only increasing that challenge. But rather than being cowed by complexity, an enlightened IT organization takes control of it, using the latest tools and techniques – and that includes application dependency mapping.

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.

What is Citrix announcing on Sept 15th?

I just did a NDA session with Citrix and was told of some really cool stuff that Citrix will be announcing. Obviously I am not at a liberty to reveal it yet but you can already start guessing. As a hint, you know where my focus is right now ;-)

Well everyone's talking about it now and you're wondering "what the heck is Linux?". So you've finally come face to face with yourself and say it loudly(errum..In your head first , please). I want to learn it! I admit it, I've been a fool! I hafta learn this kool OS! OK chill! You're faced with a challenge of all that installation crap. And boy, ask the veterans they've made lot's of money just installing Linux and installing Oracle on Linux was a big thing. And talking about setting about clusters was only for Big Boys and doing Oracle RAC setup was only for BEEEG BOYZ!!! Ok I can see you're already sleeping on my story. And Hey! Stop drooling on my shoulder! Wake up!!! You yell back at me " WHAT DO I HAFTA DO? WHERE I GOTTA KLIK? I Don't wanna fight with my wife over installing Linux at home? And my Microsoft Boss is angry because I made my colleagues so scared when I installed Linux at work? Ok Ok I get it. You want to learn it'...
