쓰리래빗츠 북의 서버 아이디는 장비 네트워크의 맥어드레스 값을 이용하여 생성하는 고유 값입니다.
VMWare인 경우에는 별도로 한번 테스트를 해보아야 할 것 같습니다.
과거에 오히려 VMWare를 사용하면 항상 같은 서버 아이디가 생성되는 문제가 보고된 적은 있습니다.
이번 경우는 오히려 반대의 현상이네요.
맥어드레스 값을 이용하는 것이라고 하니 발생 원인을 알 수 있을 것 같습니다.

해당 VM에 docker 가 구성되어 있는데, docker에서 사용하는 Interface(docker0) 의 맥어드레스가 재부팅때마다 바뀌는 것을 확인했습니다. 다른 Interface는 Virtual Box 설정 화면에서 보이는 값을 그대로 유지하고 있구요.
VM은 조금 더 공부가 필요하겠네요.
정보를 주셔서 감사합니다.
