Last year, I blogged about building a Windows cluster using VMware. Since then, new versions of VMware have made this more difficult/expensive (as it no longer works with VMware Workstation) and Rob Bastiaansen has removed the virtual SCSI disks from his website. I haven’t tried building a cluster on Microsoft Virtual Server, but it seems feasible, and a few days back, I found a Windows IT Pro magazine article on building a Windows Server 2003 cluster using Virtual Server 2005.
For anyone who says “why do this – the point about clustering is high availability and that needs the supporting hardware”, I would agree with you, but a virtual cluster is great for testing/proof of concept.
