* - Unknown nodes indicate either node IPs couldn't be discovered, or endpoints are misconfigured

NOTE:  For a full list of network IPs/interfaces, use 'svc_network list' (local) or 'svc_network list -r' (all vdcs)

此外，使用 SSH 访问远程 VDC 节点时，还需要密码：

admin@ecsnode1:~> ssh 10.x.x.x
Password:

Cause

全新安装 ECS 3.8 后，必须在 VDC 之间同步 SSH 密钥。
