我有两个带有Ceph共享存储（RBD）的计算节点1和节点2，我正在尝试设置实时迁移，但它失败并出现以下错误，不确定出了什么问题。
我正在使用 Openstack pike 16.0.16
[root@compute-01 instances]# cat /etc/libvirt/libvirtd.conf
# Ansible managed
listen_tls = 0
listen_tcp = 1
unix_sock_group = "libvirt"
unix_sock_ro_perms = "0777"
unix_sock_rw_perms = "0770"
auth_unix_ro = "none"
auth_unix_rw = "none"
auth_tcp = "none"
nova.log 中出现以下错误
如果第一次进行虚拟机实时迁移，那么它可以工作，但会抛出以下错误，并且虚拟机进入Error状态
C1 ----> C2 （第一次工作但有错误）

现在 VM 在 C2 上运行，我必须将其移回 C1，我收到以下错误，看起来 nova 在迁移 VM 后没有清理文件，或者可能是因为它处于错误状态并且没有清理以前的文件..

答案1
原始错误来自 libvirt 驱动程序调用guest.migrate_configure_max_speed：
https://github.com/openstack/nova/blob/stable/pike/nova/virt/libvirt/driver.py#L6944
直到 Pike (https://github.com/openstack/nova/commit/23446a9552b5be3b040278646149a0f481d0a005）并且它似乎没有被向后移植到 Pike，因为它在这里丢失了：
https://github.com/openstack/nova/blob/stable/pike/nova/virt/libvirt/guest.py
guest.migrate_configure_max_speed在此提交中，对驱动程序的调用已添加到：https://github.com/openstack/nova/commit/ff747792b8f5aefe1bebb01bdf49dacc01353348
您可以使用无操作手动修补 guest.py 来解决该错误：
def migrate_configure_max_speed(self, bandwidth):
pass
