[Qemu-discuss] Issue of usb emulation with qemu

[tangming]

Hi, Guys

Recentlly I have an usb emulation issue with qemu. There is one usb device on 
host, and now I need this usb device to be used by several VMs.
I enable the usb emulation with the VMs' qemu parameter "-usbdevice 
host:xxxx:xxxx", with individual qemu instance for each vm.
but seems that only one vm can use this usb normally. 

Is there any way to share the emulated usb device with two or more VMs? 
Any suggestions will be appreciated,

Best Regards,

Ming
