What are two minimum prerequisites for live migration to succeed? (Choose two.)
The correct answer is A. All AHV hosts have IP addresses in the same subnet B. All AHV hosts must be configured on the same VLAN. AHV live migration (live vMotion-equivalent) moves a running VM's state from one host to another within the same cluster. For this to succeed, all source and destination AHV hosts must meet two network requirements: (1) they must have their host IP addresses on the same subnet…

Explanation
AHV live migration (live vMotion-equivalent) moves a running VM's state from one host to another within the same cluster. For this to succeed, all source and destination AHV hosts must meet two network requirements: (1) they must have their host IP addresses on the same subnet so that the hypervisor-level migration traffic can flow directly between hosts, and (2) they must be on the same VLAN to ensure L2 adjacency for the migration data stream. The VM's IP address and VLAN configuration are irrelevant to whether the host-to-host migration channel can be established-only the hosts' network configuration matters for the migration path itself.
