"$$$. Maintenance Window Reduction - Virtual machines need maintenance but if you multiply the amount of time required to reboot individual physical systems by the number of years you service a system, the number is significant. Granted that this number is mostly Windows-oriented because patching of Linux and UNIX systems typically donâ€™t require reboots. Regardless of the operating system involved, youâ€™ll save labor hours waiting for systems to return to a usable state. VMs generally reboot in five minutes or less, while their physical counterparts can take almost a half hourâ€"depending on attached hardware and system services involved in startup."
