디스크 모드를 모두 shareable로 변경합니다.
참고로 shareable로 설정하기 위해서는 반드시 가상 디스크 드라이브를 고정 크기(Fixed)로 생성해줘야 합니다.
VM에 새로 만든 공유 디스크들을 추가합니다.
VM 설정에 들어가서 ‘저장소’ 항목으로 이동한 후에 ‘SATA 컨트롤러’옆에 있는 ‘하드 디스크 추가하기’ 아이콘을 클릭합니다.
<기존 디스크 선택하기>를 클릭합니다.
탐색창에서 생성한 디스크 이미지가 있는 경로로 찾아가서 추가할 디스크 파일을 선택한 후 <열기>를 클릭합니다.
디스크 파일이 SATA 콘트롤러에 추가된 것을 확인할 수 있습니다.
같은 방법으로 나머지 디스크들도 모두 추가하고, 완료가 되었으면 <OK>를 클릭합니다.
