Thank you for your reply.
Although qemu has usb redirection, it can not boot from the USB (install os)
however, we can boot from remote usb to install os,this is amazing function.
How do you think of this please?

qemu supports that already. It's called usb redirection.

usb redirection can use either plain tcp or a spice channel as
transport. The spice client supports usb devices on windows clients.
Hans (Cc'ed, usbredir author) looked at the USB/IP protocol and found a
number of deficits and decided to not use it because of that. I don't
remember the details though.
So I think using the existing usb redirection support is the better
option for you.
cheers,
Gerd
