3. qemu-img commit -f qcow2 2009-02-13-14-43.qcow2

4. kill -9 `ps axu|grep qemu|awk -F " " {'print $2'}`

# 이미지 축소 복사
qemu-img convert -c 원본 이미지 -O qcow2 백업 이미지

# 증분 백업
qemu-img create -b 218.236.115.207_vm38F8A.qcow2 -f qcow2 test.qcow2

1. 원본을 create 를 이용해서 백업용 이미지 생성
2. 원본을 수정후 commit
3. 원본 복구

# 복사본을 테스트 마다 새로 생성

  원본서버(on)commit  원본서버(off)commit 가상서버(on)commit 가상서버(off)commit
원본 서버   원본데이터복사               이상없음                                                     

가상서버             변화 없음              원본데이터복사                                                          

# 복사본을 2개 만들경우
commit(우선)  
test(변경전)   원본복구안됨(test 이미지도 삭제 이미지로 변경됨)
test2(변경후(데이터 삭제))
==================================
# 복사본을 만들때 원본 데이터 수정후 가상서버 정지!
