CDI提供了使用PVC作为虚拟机磁盘的方案，在虚拟机启动前通过下面方式填充PVC:
- 通过URL导入虚拟机镜像到PVC，URL可以是http链接，s3链接
- Clone一个已经存在的PVC
- 通过container registry 导入虚拟机磁盘到PVC,需要结合ContainerDisk使用
- 通过客户端上传本地镜像到PVC
通过virtctl，结合CDI可以上传本地镜像到pvc上，支持的镜像格式有：
- .img
- .qcow2
- .iso
2.创建虚拟机：上传虚拟机镜像到服务器：
查看cdi-uoloadproxy的service ip :
# kubectl -n cdi get svc -l cdi.kubevirt.io=cdi-uploadproxy
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
cdi-uploadproxy ClusterIP 172.10.212.21443/TCP 3d1h
查看sc名称（上篇文章创建的）：# kubectl get sc
NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE
rook-ceph-block rook-ceph.rbd.csi.ceph.com Delete Immediate true 2d7h
将windows镜像上传到PVC：# virtctl image-upload --uploadproxy-url=https://172.10.212.21 --pvc-name=iso-win10 --pvc-size=10Gi --insecure --storage-class=rook-ceph-block --access-mode=ReadWriteMany --block-volume --image-path=./cn_windows_10_business_editions_version_1909_updated_jan_2020_x64.iso
PVC default/iso-win10 not found
PersistentVolumeClaim default/iso-win10 created

- --image-path：操作系统镜像地址。
- --pvc-name：指定存储操作系统镜像的pvc，pvc动态创建。
- --pvc-size：pvc大小，根据操作系统镜像大小来设定，一般比上传操作略大就行。
- --uploadproxy-url：cdi-uploadproxy的service Ip。
