apt-get install -y nova-api nova-cert nova-common nova-compute nova-compute-kvm nova-doc nova-network nova-objectstore nova-scheduler nova-volume Python-nova python-novaclient nova-consoleauth python-novnc novnc
2：配置 /etc/nova/nova.conf
把nova.conf 原来的内容删除掉。直接贴下面内容。重点需要注意的是，
如果你是在虚拟机里测试Openstack。你需要把默认的虚拟化引擎从kvm改成qemu。
nova的配置，等下再补上。

3：配置/etc/nova/api-paste.ini
也是修改文件最后3行，
admin_tenant_name = %SERVICE_TENANT_NAME%
admin_user = %SERVICE_USER%
admin_password = %SERVICE_PASSWORD%
改成
admin_tenant_name = admin
admin_user = admin
admin_password = admin
4：停止和重启nova相关服务
for a in libvirt-bin nova-network nova-compute nova-api nova-objectstore nova-scheduler novnc nova-volume nova-consoleauth; do service "$a" restart; done
5：同步数据库
nova-manage db sync
没有任何输出，就表示正常。
6：创建网络
nova-manage network create private --fixed_range_v4=10.10.10.32/27 --num_networks=1 --bridge=br100 --bridge_interface=eth1 --network_size=32
nova-manage floating create --ip_range=172.16.10.32/27
检查nova服务
nova-manage service list
看到这样，就表示你的nova服务正常。
