Each Linux BuildVM clone gets a new SSH host key for the same NAT IP, causing 'host key has changed' errors with accept-new mode. After IP detection, ssh-keygen -R removes the old entry from the CI-local known_hosts file (F:\CI\State\known_hosts by default) before Phase 4/5 make any SSH connection. The file is created if it does not exist yet. Windows jobs are unaffected.
