Which of the following is a feature of virtualization that can potentially create a single point of failure?

Server consolidation places multiple VMs onto a single physical host to maximize hardware utilization. If that physical host experiences a hardware failure, power outage, or OS crash, every VM running on it goes offline at the same time. This dependency on a single physical machine for multiple workloads is a classic single point of failure introduced by the consolidation model.

Load balancing hypervisors distribute VM workloads across multiple physical hosts, which actively reduces single points of failure rather than creating them.

Faster server provisioning through VM templates and cloning is an operational efficiency benefit of virtualization and does not introduce hardware dependencies or availability risks that constitute a single point of failure.

Running multiple OS instances is the core capability of a hypervisor, but the single point of failure risk arises specifically from consolidating those instances onto a single physical machine, not from the ability to run multiple OS instances itself.
