Q: How is virtualization like a dual-boot system?

A: It is nothing like a dual-boot system. A dual-boot system still runs only one OS at a time, has no idealized hardware environment, and provides no encapsulation or portability.

Q: What do you mean virtual machines are portable?

A: Because virtual machines are encapsulated in their .vmdk files and VMware provides an idealized hardware environment, virtual machines can be moved from one ESX Server to the next either using Vmotion or importing the .vmdks.

Q: How is VMware more stable than, say, a new physical server?

A: The idealized hardware provided by VMware provides a consistent virtual hardware environment that increases that stability of your virtual machines independent of the underlying physical hardware.
