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.

There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:

2) booting and partitioning software from other OSs
