我已经使用 devstack 脚本安装了多节点 openstak。可以运行虚拟机，但存在网络问题，无法从一个虚拟机 ssh/ping 到另一虚拟机。我只能从运行该虚拟机的主机（control1、computeX）通过 ssh 连接到虚拟机，而从其他主机则不能。有什么建议么？

您可能需要向默认 OpenStack 安全组添加规则以启用 ping 和 SSH：
nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
nova secgroup-add-rule default tcp 22 22 0.0.0.0/0
第一条规则为 VM 实例启用 Internet 控制消息协议 (ICMP)（ping 命令）。第二条规则通过 22 端口启用 TCP 连接，该端口由 SSH 使用。
