轉換 KVM 使用 Spice

1. 安裝 Spice

   [root@dywmsi ~]# yum install spice-server spice-client spice-protocol
   

2. 關閉 VM ，改變設定，再開啟 VM，才會生效，所以先關閉 VM kvm8。

   [root@dywmsi ~]# virsh destroy kvm8
   Domain kvm8 destroyed
   

3. 圖形界面開啟應用程式：

   Virtual Machine Manager
   選點要修改的 VM
   Show virtual machine detail
   Display --> Spice
   

4. 比較修改前後的 xml：

   [root@dywmsi ~]# diff -uN kvm8.xml.bak /etc/libvirt/qemu/kvm8.xml 
   --- kvm8.xml.bak	2019-10-28 17:43:25.686329429 +0800
