配置Ceph为glance****镜像的后端存储（节后参考）

编辑/etc/glance/glance-api.conf

[glance_store]

stores = rbd

default_store = rbd

rbd_store_pool = images

rbd_store_user = glance

rbd_store_ceph_conf = /etc/ceph/ceph.conf

rbd_store_chunk_size = 8

如果你想允许用image的写时复制克隆，再添加下列内容到[DEFAULT]段下：

show_image_direct_url = True

建议把如下属性也加上，加到[default]下：

hw_scsi_model=virtio-scsi #添加 virtio-scsi 控制器以获得更好的性能、并支持 discard 操作

hw_disk_bus=scsi #把所有 cinder 块设备都连到这个控制器；

hw_qemu_guest_agent=yes #启用 QEMU guest agent （访客代理）

os_require_quiesce=yes #通过 QEMU guest agent 发送fs-freeze/thaw调用

测试下上传镜像：

如果镜像cirros-0.3.5-x86_64-disk.img是qcow2格式的，可以先将它转换成raw格式的，因为如果要使用ceph作为后端存储，就应该将它的镜像格式转为raw：

可以使用命令qemu-img info cirros-0.3.5-x86_64-disk.img查看它是什么格式的，使用命令将它从qcow2格式转换成raw格式并保存成另外一个镜像文件：

qemu-img convert -f qcow2 -O raw cirros-0.3.5-x86_64-disk.img image.img

以下进行上传镜像操作：

. admin-openrc.sh

glance image-create --name “imagetest” --file image.img --disk-format raw --container-format bare --visibility public --progress

使用如下命令验证是否创建成功：

openstack image list
