+9f6226a7  +  9f862687 = good
+
+
+
+Reproduce steps:

+1. create guest
+qemu-system-x86_64 --enable-kvm -m 1024 -smp 4 -net none rhel6u5.qcow -monitor pty
+2. hot add the vf to guest
+echo "device_add pci-assign,host=05:10.0,id=nic" >/dev/pts/x
+cat /dev/pts/x
+3. hot remove the VF froem guest
+echo "device_del nic" >/dev/pts/x
+
+Current result:

+the guest willl be destroyed after hot remove the VF from the guest
+
+Expected result:
+----------------
+the guest works fine after hot remove the VF from the guest
