P2V as a Part of Forensics

Posted Jan 16, 2009 - 04:30 pm

Recent VMware Communities forum discussions have brought Forensics to the fore once again. Even so it has made me think of using virtualization tools to do preliminary analysis -- something that could tell you if the time and effort of full acquisition is required.

Forensics and Dedupe

Posted Nov 10, 2008 - 01:37 pm

Disk deduplication (Dedupe) is a forensically untried solution to the need for more disk space within data centers. Untried does not mean unsound, but until the forensic science can catch up with the technology there may be issues.

VMware HA failed with error....

How to fix the cryptic VMware HA failed with error messages. This is a caustic error that actually has no real meaning other than to say VMware HA could not start, but not actually why!

Understanding VMware EVC

Posted Oct 17, 2008 - 10:03 am

Many people are confused about VMware EVC and how to configure this on their systems. When most people go to configure EVC they attempt to turn it on and get this hardware does not support EVC. Which is untrue for 98% of the attempts. There is more to enabling EVC than many realize.
VMware HA Fixed for SMB 2 node clusters

Posted Oct 05, 2008 - 11:19 am

VMware HA was busted when VMware ESX 3.5 Update 2 was applied. VMware HA would fail to fire when a node was down, fail to evacuate VMs when entering maintenance mode, and fail to start VMs, with a not enough resources error, if the second node was down. This all applied to the SMB two node cluster world. With VMware Virtual Center 2.5.0 Update 3 and the 10/3/08 patches for ESX this is now fixed.

VMworld and Forensics

Posted Sep 23, 2008 - 10:29 am

In discussions with backup companies about digital forensics I discovered some useful items. Specifically that full VMDK backups may be forensically sound and that there is a way to dump the memory of a VM before you kill it like pulling the plug.
