Benchmarking with VMmark on new hardware



Bruce Herndon tries out the VMmark on new hardware.

These two different disk configurations highlight some interesting tradeoffs and tuning opportunities exposed by VMmark. The single LUN configuration utilizing six disks has the benefit of providing high disk throughput for one VM at the expense of scalability if multiple disk-intensive VMs are running. On the other hand, creating multiple LUNs provides both good predictability and excellent scaling but limits the total throughput of any single VM by providing only a subset of the hardware resources to each one. From a benchmarking perspective, the multi-LUN approach is clearly better since it results in a higher overall score.


Honestly, we have reported several benchmarks and tools being used were either beta or some of them reported results that really didn't matter. VMware is also a member of the SPEC committee but still results like these speak volumes.

Benchmarking is not about VMware is better than Parallels is better that Xen is better than whatever. It is about telling the customer to be careful when applying and deploying certain scenarios. VMware is doing a pretty good job at it.

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
