Exceeded maximum number of retries. Exhausted all hosts available for retrying build failures

openstack由于cpu未开启虚拟化,导致创建实例失败原因分析

cpu虽然支持vmx,但主板未开启,安装完openstack出现莫名其妙问题。

openstack控制台错误如下:

消息 Exceeded maximum number of retries. Exhausted all hosts available for retrying build failures for instance 7c4394d1-c7ef-4cff-9d32-4d91c2c87617. 编码 500 详情 File "/usr/lib/python2.7/site-packages/nova/conductor/manager.py", line 580, in build_instances raise exception.MaxRetriesExceeded(reason=msg) 已创建 June 25, 2018, 12:06 p.m.

####

解决办法:

方法1:修改/etc/nova/nova.conf,增加

[libvirt]virt_type = qemu方法2:开启主板cpu虚拟化功能
