If you understand just fine, why are you talking about Linux and 
Windows? VMware vSphere uses neither. You can also use a BSD-based 
hypervisor or Xen using NetBSD for drivers. All these methods keep you 
away from Linux and Windows.

No. With vSphere you can even run an OS instance on two physical 
machines at once. If one of them fails, all those VMs will keep running 
on the other metal. There will not be any interruption.

For planned hardware outages, you can migrate running VMs to other hardware.
