eXludus and VMware on Adaptive Virtualization



Really cool.

In collaborative tests conducted on the White Rose Grid cluster at York, RepliCator’s prototype Virtual Provisioning Optimizer capability and VMware software were employed to create a virtual container within the cluster's native 64-bit Linux environment. Within this virtual container, RepliCator then launched the popular NCBI – BLAST application with its own 32-bit Windows Vista operating environment.

Both the Vista virtual environment of 6 GB per image and 1 GB of human genome data were provisioned with RepliCator parallel file serving to all cluster nodes simultaneously. A total of approximately 100 GB was provisioned in under 4 minutes to all nodes across Gigabit Ethernet. Provisioning with RepliCator occurs asynchronously, overlapped with other computation so processing never stalls for network I/O. With RepliCator, virtual provisioning is no longer inevitably associated with performance-degrading overhead. RepliCator removes a significant barrier to wider adoption of virtualization on clusters.

In the same tests, RepliCator's parallel file serving capability enabled the BLAST application and its Windows environment, still within the virtual container, to scale across the cluster with high efficiency. The virtually provisioned RepliCator-Vista application scaled linearly without degradation, while the same application run with NFS in the native Linux environment suffered significant performance degradation.


It is indeed time to make it so lethal that high I/O intensive apps, RAC, fat GUI apps, all will run happily on the hypervisor!

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...
