解决方法

##1.在所有控制节点和计算节点配置免密钥通信

https://www.cnblogs.com/omgasw/p/13453462.html

##2.在计算节点添加以下配置

openstack-config --set /etc/nova/nova.conf DEFAULT allow_resize_to_same_host True
openstack-config --set /etc/nova/nova.conf DEFAULT scheduler_default_filters RetryFilter,AvailabilityZoneFilter,RamFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,ServerGroupAntiAffinityFilter,ServerGroupAffinityFilter

##3.重启服务

systemctl restart openstack-nova-compute.service
