OpenStack 创建虚拟机错误：Exceeded maximum number of retries. Exhausted all hosts available for retrying bui
2024-05-17 04:14:35
错误
Ubuntu 20.04 下手动安装 OpenStack Xena 版
在创建虚拟机的时候总是失败
openstack server create --flavor m1.nano --image cirros.0.5.2 --nic net-id=1e46c104-a455-4875-a920-e0b9a2d59e73 --security-group default --key-name mykey provider-instance
命令行方式下，也不知道这个错误应该是查询 /var/log/nova 下的哪一个，继续安装 DashBoard 之后查看
查找原因
在 dashboard 上很容易就看到了
消息Exceeded maximum number of retries. Exhausted all hosts available for retrying build failures for instance 3ac51153-78ca-4127-9824-fcdce6768859.编码500详情Traceback (most recent call last): File "/usr/lib/python3/dist-packages/nova/conductor/manager.py", line 669, in build_instances raise exception.MaxRetriesExceeded(reason=msg) nova.exception.MaxRetriesExceeded: Exceeded maximum number of retries.

想到 Controller 节点是不是也存在这个文件 vim /etc/nova/nova-compute.conf 果然也是有的
是不是我安装过程中发生过什么错觉， Controller 节点也安装了 Compute 节点的东西？不记得了！
反正照方抓药，也改成 virt_type = qemu
然后，也是 service nova-compute restart再次创建，就 OK 了！
后记
命令行方式下，也不知道这个错误应该是查询 /var/log/nova 下的哪一个,那就 grep 试试
root@controller:/var/log/nova# grep -nr Exceeded *
