1，需求如下：短信机的使用的传统型的串口，想连接到业务，并能够根据业务设置发送短信。业务服务为kvm上运行的虚拟机，但kvm上没有添加usb1.0的接口，所以只能通过自己编写xml的方式，在挂载usb串口。2，登录服务器使用如下命令查看usb的型号和类型：
[server1]#lsusb
Bus 002 Device 002: ID 8087:8002 Intel Corp.
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 8087:800a Intel Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 002: ID 3689:8762
Bus 003 Device 005: ID 096e:0006 Feitian Technologies, Inc.
Bus 003 Device 009: ID 0403:6001 Future Technology Devices International, Ltd FT232 Serial (UART) IC
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub根据ID 0403:6001 Future Technology Devices International, Ltd 查找x相对应的Vendor和product。
[server1]#lsusb -v |grep 0403
idVendor 0x0403 Future Technology Devices International, Ltd
[server1]#lsusb -v |grep 6001
Bus 003 Device 009: ID 0403:6001 Future Technology Devices International, Ltd FT232 Serial (UART) IC
idProduct 0x6001 FT232 Serial (UART) IC编写xm文件样例如下
[server1]#vim usb.xml
<hostdev mode=‘subsystem‘ type=‘usb‘ managed=‘yes‘>
<source>
<vendor id=‘0x0403‘/>
<product id=‘0x6001‘/>
<!--address bus=‘3‘ device=‘3‘/-->
</source>
<alias name=‘hostdev10‘/>
</hostdev>使用virsh list查看虚拟机的uuid
[root@ceph-4 ~]# virsh list
Id Name State
