Virtualization 2.0, Virtualiztion 3.0: Hu Yoshida has it all figured out

Hu talks about it here:

I believe the next step is capacity virtualization, or thin provisioning. This year Hitachi introduced the USP V which added Dynamic Provisioning on top of the capability to virtualize external storage. Dynamic Provisioning is the ability to provision physical storage when it is actually used, not when it is allocated. It eliminates the waste of allocated but unused capacity which some estimate to be 60% or more of the average storage allocation. It can also eliminate that waste from all the copies that are usually made for backup cycles, business continuance, data mining, development and test, and data distribution. This type of virtualization also enables a volume’s capacity to be automatically leveled across many spindles of RAID protected disks, which reduces management complexity and distributes the I/O load across many more physical disk arms in order to compensate for limitations of larger and slower disks.

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
