What is the drawback of virtualization?

Virtualization has its own drawback: the need to restructure the approach to working with system reliability. Indeed, since several virtual machines are running on the same physical server, failure of the host leads to the simultaneous failure of all VMs and the applications running on them.

What is virtualization in simple words?
