飞腾D2000 UOS下安装KVM虚拟机

其他的和x86环境都差不多，开了开发者模式后，virt-manager  qemu-efi-aarch64 qemu-system 几个包补齐，启动libvirtd服务，查看日志，报以下日志，

同时,virt-manager图形面板无法创建qemu的虚拟机

百度了下，有人提到cpu_map

虽然有x86的配置文件，但确实不知道啥格式，直接查看官网最新的源码示例

 cat /usr/share/libvirt/cpu_map/ft_d2000.xml 
<cpus>

这个其实是飞腾CPU的型号架构代号。

写好后重启libvirtd服务就OK了
