A hypervisor administrator needs to move a running production VM from one physical host to another for scheduled hardware maintenance without causing any noticeable downtime or interruption to end users. Which capability enables this?
- AVM snapshot
- BVM cloning
- CLive migration
- DVM templating
Show answer & explanationAnswer & explanation
Correct answer: C. Live migration
Live migration allows a running VM to be moved between physical hosts while it continues to operate, with minimal to no downtime, making it ideal for hardware maintenance scenarios.
Why the other options are wrong
- A. A snapshot preserves a point-in-time state but does not move a VM between hosts.
- B. Cloning creates a separate copy of a VM, not a live move of the running instance.
- D. Templating is used to standardize new VM deployments, not to relocate a running VM.
Live Migration
The process of moving a running VM from one physical host to another with little to no downtime, often used for maintenance or load balancing.
- Requires shared storage or fast network transfer between hosts
- Preserves VM state and active connections
- Common feature in enterprise hypervisors (e.g., vMotion, Hyper-V Live Migration)
Memory trick: Live migration is a moving truck that never stops the show.
