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)

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
