使libvirt识别nova密钥

  • 确保文件在节点可用:
  • /etc/ceph/ceph.conf
  • /etc/ceph/client.nova.keyring
chown nova:nova /etc/ceph/ceph.client.nova.keyring
chmod 640 /etc/ceph/ceph.client.nova.keyring

# 生成uuid
uuidgen

# 创建密钥配置文件
vim secret.xml

<secret ephemeral='no' private='no'>
<uuid>上面的uuid</uuid>
  <usage type='ceph'>
    <name>client.nova secret</name>
  </usage>
</secret>

# 按照配置文件导入密钥
virsh secret-define --file secret.xml
# 查看nova用户的密钥
ceph auth get-key client.nova
# 注入密钥
virsh secret-set-value --secret <uuid> --base64 <nova.key>

在一个节点执行

# 初始化API数据库
su -s /bin/sh -c "nova-manage api_db sync" nova
# 创建cell0、cell1数据库
# cell0：只记录调度失败的实例信息
# cell1：计算资源池正常的实例
su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
# 同步主数据库
su -s /bin/sh -c "nova-manage db sync" nova
