Of course, saying that VM solves our HA/DR problems like so much secret sauce is BS without making the application resilient to the same kind of problems that can happen to bare metal such as unexpected crashes and some way to handle DR which is very different than HA.
Actually VMware does have a feature now called Fault Tolerance where a VM is run in lockstep on two different nodes in a cluster. They are kept running the same instruction for instruction AFAIK so there would be no time warp during a failover event, there are some product demos on youtube showing them playing a video file over a remote desktop and it not skipping a frame while failing over. That could work as an HA solution but would do nothing for DR.
