Implementing a Multi-Node Hypervisor Cluster on a Single Desktop Running VMware Workstation 8

As a field consultant for the last several years, I have been amazed at the numerous deployment scenarios that can be reproduced utilizing just one piece of physical hardware. Due to increasingly expensive electrical bills I trimmed down my server class lab hardware nearly a year ago in favor of a megadesktop that could handle anything I threw at it. While dual-, tri- and quad-boot scenarios have given me the ability of running ESXi, XenServer, Hyper-V, and Windows 7 natively on the hardware, it has been difficult to reproduce complex multi-node hypervisor cluster scenarios without wrangling additional equipment. With the [...]

Automated Migration to VMxNet3 Network Adapters and Paravirtual SCSI Controllers for vSphere 4.x Virtual Machines

VMware vSphere 4.x was released for general availability nearly two years ago and now vSphere 5.x is rumored for release later this year. In June 2009, virtualization master Scott Lowe wrote a blog post illustrating the roughly 16 manual steps to upgrade virtual machines to VMxNet3 adapters and Paravirtual SCSI (PVSCSI) controllers. Interestingly, two years following I still encounter larger environments that are not fully taking advantage of the performance characteristics of these two virtual machine hardware types. The reason is simple, this 16 step process can take up to 30 minutes of downtime per virtual machine if done manually, [...]
