当批量删除虚拟机时报错如下
1、在计算节点的报错信息如下

解决方法设置neutron配置文件中的如下参数
openstack-config --set /etc/neutron/neutron.conf DEFAULT api_workers 20
openstack-config --set /etc/neutron/neutron.conf database max_overflow 2000
openstack-config --set /etc/neutron/neutron.conf database max_pool_size 2000
openstack-config --set /etc/neutron/neutron.conf database retry_interval 2
设置nova的配置文件如下
openstack-config --set /etc/nova/nova.conf database max_pool_size 2000
openstack-config --set /etc/nova/nova.conf database max_retries 10
openstack-config --set /etc/nova/nova.conf database retry_interval 5
openstack-config --set /etc/nova/nova.conf database max_overflow 2000
