jfruh writes The ability to cram multiple virtual servers on a single physical computer is tempting — so tempting that many shops overlook the downsides of having so many important systems subject to a single point of physical failure.

    Put all your eggs in one basket.

    Hyper-V High Availability Cluster. It's right there in Windows Server. Other OS's have similar capabilities.

    Virtualise everything (there are a lot more advantages than mere consolidation - you have to LOVE the boot-time on a VM server as it doesn't have to mess about in the BIOS or spin up the disks from their BIOS-compatible modes, etc.), then make sure you replicate that to your failover sites / hardware.
