我已经按照官方指南安装了 OpenStack Victoriahttps://docs.openstack.org/install-guide/index.html
但是如果我现在在公共网络中启动虚拟机，它会失败并出现错误。
/var/log/nova/nova-compute.log 中的日志提示了网络接口分配问题。由于这提示了 Neutron 的问题，因此这是来自 /var/log/neutron/linuxbridge-agent.log 的日志

有人知道那里出了什么问题吗？如果需要更多信息，请告诉我要提供什么。谢谢。
答案1
我也遇到了同样的问题。经过几天的时间，阅读了数十亿条 Google 搜索结果，我找到了解决方案：
禁用 IPv6
编辑/etc/sysctl.conf并加载它sysctl -p：
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
不，我确实如此不是知道为什么 IPv6 会导致失败...
答案2
我没有足够的声誉点来发表评论（提示！提示！），所以我正在写一个答案，尽管这可能无法解决你的问题。
有一个英文网页同时报道了“代理循环错误“ 和 ”没有权限“。通过重新安装 Neutron 解决了该问题：https://ask.openstack.org/en/question/121433/openstack-rocky-vm-not-spawning-on-provider-network-though-it-is-successfully-getting-spawned-on-self-service-network。
