RHEL-7 qemu should do tghis correctly, patch is upstream.

Comment 2 Sibiao Luo 2013-07-08 06:46:36 UTC
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.

Best Regards,
