Virtualization advices keep pouring in...



"We've been well past the development/QA stage...". A lot of folks start off like that. Insufficient (or even none!) feedback keeps those virtualization solutions in the labs. It is very important that the managers pull up their socks and start reporting back to their bosses. (For the very same reason the CIOs too must take serious interest in these matters!)

All I want to say is that virtualization is running in production of companies like Google (and these guys run some real stuff there). The virtualization has been running in production for quite many years. Anyways if you're still a newcomer then an advice like this will help you decide:

Instead, you can have each app on its own virtual server, and put them all on one or more physical machines -- however many are needed to run the apps effectively. Costs are reduced since you have fewer machines to power, watch, store, and maintain. Scaling applications can be simplified since you can allocate more or fewer resources to specific vitual servers, and you can always move them onto other, more powerful physical machines as your needs grow. Plus, disaster recovery can be easier, since if you have a hardware failure, you can just load the virtual server onto a different machine and keep on truckin'.

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...
