verify this issue on qemu-kvm-1.5.1-2.el7.x86_64, the QEMU did not core dump and will prompt that the device 'usb-ehci'|'nec-usb-xhci' does not support hotplugging. But for there is still prompt that 'An undefined error has occurred', please refer to existing bug 949211. host info: 3.10.0-0.rc7.64.el7.x86_64 qemu-kvm-1.5.1-2.el7.x86_64 guest info: 3.10.0-0.rc7.64.el7.x86_64 # /usr/libexec/qemu-kvm -M pc-i440fx-rhel7.0.0 ....-device nec-usb-xhci,id=xhci,bus=pci.0,addr=0x8 -device usb-ehci,id=ehci,bus=pci.0,addr=0x9 (qemu) device_del ehci Device 'usb-ehci' does not support hotplugging An undefined error has occurred (qemu) device_del xhci Device 'nec-usb-xhci' does not support hotplugging An undefined error has occurred Base on above, this issue has been fixed, set to verified status. please correct me if any mistake.
