Required Packages
On both Control & Compute:
1
yum install spice-html5
注意点
spice-html5 在epel源里，需要配置epel源

Config Files
The file to modify is
/etc/nova/nova.conf
in compute and control nodes.
In both config files, ensure vnc_enabled=False is explicitly set. If novnc is enabled, ensure that is disabled too.(在这里把enabled=False即可)
Control IP = 192.168.1.100
Compute IP = 172.16.1.100 [Internal IP - ports may need to be opened if not already there]
On Control Node
/etc/nova/nova.conf
[DEFAULT]
web=/usr/share/spice-html5

1
iptables -I INPUT -p tcp -m multiport --dports 6082 -m comment --comment "Allow SPICE connections for console access " -j ACCEPT
永久设置iptables
You can make permanent by adding the above rule to /etc/sysconfig/iptables (before the reject rules) saving and restarting iptables.

在Control node上看到6082端口在监听
虚拟机需要重启才能使用spice协议
OpenStack中的windows7播放视频，有点卡，由于在服务器中图像处理都是CPU来做的，需要优化spice协议
