VMWare Enterprise Suite allows you to use vmotion in the event of a total hardware failure, as long as your Disk/Data is in a NAS or SAN. If you save all of your Virtual Machines hard disks locally then yes in the event a system board fails, you are out of luck.
Although vmotion with attached SAN or NAS where your hard disks live. You can have a full system board failure from a host, and the Guest (Virtual Machine) will live migrate. You can find the full vmotion_datasheet.pdf by googling it. (Wasn't sure if i could provide the link, sorry
Keep in mind VMWare is expensive over $10,000/year for licensing + infrastructure. I find that the Cisco UCS Chasis work the best for VMWare if any of you are considering this option.
Definition for those who don't know.
NAS - Network Attached Storage
SAN - Storage Area Network
