libvirt 无法创建ceph存储池

Question

使用virsh命令创建ceph存储池报错

步骤：
1.生成secret

#virsh secret-define secret.xml
<uuid of secret is output here>
#virsh secret-set-value --secret $uuid --base64 $ceph admin key

2.创建pool

#virsh pool-define cephpool.xml
#virsh pool-start cephpool1

报错：

# virsh pool-start cephpool1
error: Failed to start pool cephpool1
error: failed to stat the RADOS pool 'rbd': Connection timed out
