Live migration involves transferring a running virtual machine (VM) from one physical host to another with no downtime. For this to succeed, the destination host must be compatible with the source. The CPU architecture (e.g., x8664) must match, as the VM's running processes cannot be transferred to an incompatible instruction set. Additionally, the destination host must have enough available physical memory to accommodate the VM's allocated RAM. Without sufficient memory, the VM cannot be started on the new host.

A. The presence or type of physical USB ports on the host servers is not a requirement for a standard live migration.

B. While mismatched network speeds can affect migration performance, they do not prevent the migration from being possible.

C. Available swap space on the host is a system resource, but it is not a direct compatibility requirement for the VM state transfer.

F. For live migration, VMs typically use shared storage, so both hosts must have access to it, but their local disk storage paths do not need to match.

"Migration prerequisites and limitations

" states: "The source and destination hosts must have the same CPU architecture" and "The destination host must have enough free RAM to run the migrated virtual machine."

it lists "Compatible processors" and "Sufficient resources on the target host" as key requirements.
