Jonathan Schwartz to lay out Sun's Virtualization Strategy at OOW

With its hypervisor, Sun looks to aid users who might have a datacenter full of small servers, each running a separate application and perhaps in use only at a certain time of the day or month, said Wilson. The average utilization of these machines is very low with customers only using 10 percent of available compute cycles.

"The idea is that the xVM Server software, which is the hypervisor software, will allow customers to take various workloads, including applications written to Solaris and Linux and Windows, and run them simultaneously on the same hardware," Wilson said.

Featured in xVM Server is work from the Xen open-source community. Through xVM Server, Sun will extend Solaris technologies, such as Predictive Self-Healing and ZFS (Zettabyte File Server) to Windows and Linux.

Sun previously has offered its Logical Domains (LDOMs) hypervisor, but it only supported SPARC CPUs. The new hypervisor extends to x86/64 systems.

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!
