OpenStack : 원시 디스크 형식의 인스턴스 시작

Question

내 OpenStack에 두통이 있습니다. 내가 뭘 하려는지 디스크가 기본 qcow 대신 원시 형식으로 인스턴스를 만드는 것입니다.

인스턴스를 만들려고하는 원본 디스크 이미지 역시 원시 형식입니다. 나는 통해 이미지를 만들었습니다

openstack image create --public --disk-format raw --container-format bare --file CentOS-7-x86_64-GenericCloud-1710.raw CentOS_7_raw 

하지만 그것에서 인스턴스를 시작할 때 디스크가 Qcow2 (V3) 형식으로 변환되는 것을 알 수있다.

원시 형식의 디스크로 인스턴스를 실행할 가능성이 있습니까? 눈에

1. 이미지 업로드 :

   # openstack image create --public --disk-format raw --container-format bare --file CentOS-7-x86_64-GenericCloud-1710.raw CentOS_7_raw

   | visibility  | public            | 
   +------------------+------------------------------------------------------+ 
   

2. 변경 /etc/nova/nova.conf.

   # VM Images format. If default is specified, then use_cow_images flag is used 
   # instead of this one. (string value) 
   # Allowed values: raw, qcow2, lvm, rbd, ploop, default 
   #images_type=default 
   images_type=raw 
   

3. 다시 시작 노바 : images_type 매개 변수 raw에 업데이트

   # openstack-service restart nova 
   # openstack-service status nova 
   MainPID=1485 Id=openstack-nova-api.service ActiveState=active 
   MainPID=1500 Id=openstack-nova-cert.service ActiveState=active
