v8.1.3在鲲鹏920平台上似乎不支持虚拟机在线热添加CPU/内存

[zhufeng]

Describe the bug
1、正常创建虚拟机，VM操作系统使用麒麟v10 sp3。
2、在VM设置中，开启热添加CPU/内存，同时开启虚拟机CPU的NUMA。
3、VM开机之后，直接报错：
kvm: -device host-x86_64-cpu,id=cpu2,socket-id=0,core-id=1,thread-id=0: 'host-x86_64-cpu' is not a valid device model name TASK ERROR: start failed: QEMU exited with code 1
4、将CPU/内存热添加的勾去掉之后，能正常开机。

To Reproduce
如上。

Expected behavior
VM正常热添加CPU/内存。
