The steps of tested: 1. start a vm using below qemu command line: ./qemu-system-x86_64 -enable-kvm -m 4096 -smp 4 -name win7 -boot c -drive file=/mnt/sdb/gonglei/image/win7_32_2U -vnc 0.0.0.0:10 -monitor stdio 2. hot-plug/unplug an usb host adapters: 2.1) For ehci: (qemu) device_add usb-ehci,id=ehci (qemu) device_add usb-tablet,id=input0,bus=ehci.0,port=1 (qemu) device_del ehci 2.2) For uhci: (qemu) device_add piix3-usb-uhci,id=uhci (qemu) device_del uhci 2.3) For uhci: (qemu) device_add pci-ohci,id=ohci (qemu) device_del ohci 2.4) For uhci: (qemu) device_add nec-usb-xhci,id=xhci (qemu) device_del xhci 3. do step #2 repeating, more than 20 times. BTW, I will add some qtestes for usb host adapters hot-plug/unplug later, and add tracing for exit function. Best regards, -Gonglei
