由于 sftp 子系统错误，Openstack nova 冷迁移在 rocky 9 上失败

  • 772

我已经在 2 台 rocky linux 9.1 机器上使用 kolla ansible（按照 openstack 部署指南部署）部署了 OpenStack 的多节点部署。当尝试在节点之间迁移一个实例时，失败并且实例进入错误状态。我在日志中收到以下错误：

我的假设是某处服务器和客户端之间存在一些不匹配，一个使用旧版 scp，另一个使用 sftp，但是我不确定如何纠正这个问题。

    Subsystem       sftp    /usr/libexec/openssh/sftp-server

    并/etc/kolla/nova-ssh/sshd_config重新启动 nova_ssh 容器可以解决这个问题。
