1、删除的computer节点的虚机
2、删除用户下所有实例
3、nova service-list
nova service-disable uzer-kvm-5 nova-compute
nova service-disable uzer-kvm-6 nova-compute
4、删除数据库对应信息
use nova;
select host from services;
delete from serivces where host="uzer-kvm-5";
delete from serivces where host="uzer-kvm-6";
select host from compute_nodes;
delete from compute_nodes where host="uzer-kvm-5";
delete from compute_nodes where host="uzer-kvm-6";
5、查看是否删除成功
nova service-list
