Openstack nova冷迁移在rocky 9上由于sftp子系统错误而失败
提问于 2023-02-02 00:13:21
我使用kolla (按照OpenStack部署指南部署)在2台LOCKLinux9.1机器上部署了openstack的多节点部署。当试图在节点之间迁移一个实例时，它会失败，并且该实例进入错误状态。我在日志中得到以下错误：

2023-01-30 14:52:49.767 7 ERROR oslo_messaging.rpc.server我的假设是，服务器和客户机之间存在一定的不匹配，其中一个使用遗留scp，另一个使用sftp，但是我不知道如何纠正这一点。

附加
Subsystem sftp /usr/libexec/openssh/sftp-server要重新启动/etc/kolla/nova-ssh/sshd_config并重新启动nova_ssh容器，就可以解决这个问题。
