+[Qemu-devel] [BUG] vhost-user: hot-unplug vhost-user nic for windows guest OS will fail with 100% reproduce rate
+
+Hi, guys
+
+I met a problem when hot-unplug vhost-user nic for Windows 2008 rc2 sp1 64 
+(Guest OS)
+
+The xml of nic is as followed:
+<interface type='vhostuser'>
+  <mac address='52:54:00:3b:83:aa'/>
+  <source type='unix' path='/var/run/vhost-user/port1' mode='client'/>
+  <target dev='port1'/>
+  <model type='virtio'/>
+  <driver queues='4'/>
+  <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/>
+</interface>
+
+Firstly, I use virsh attach-device win2008 vif.xml to hot-plug a nic for Guest 
+OS. This operation returns success.
+After guest OS discover nic successfully, I use virsh detach-device win2008 
+vif.xml to hot-unplug it. This operation will fail with 100% reproduce rate.
+
+However, if I hot-plug and hot-unplug virtio-net nic , it will not fail.
+
+I have analysis the process of qmp_device_del , I found that qemu have inject 
+interrupt to acpi to let it notice guest OS to remove nic.
+I guess there is something wrong in Windows when handle the interrupt.

+[Qemu-devel] [BUG] network : windows os lost ip address of the network card  in some cases
+
+we  found this problem for a long time 。For example, if we has three network 
+card in virtual xml file ，such as "network connection 1" / "network connection 
+2"/"network connection 3" 。
+
+Echo network card has own ip address ，such as 192.168.1.1 / 2.1 /3.1 , when 
+delete the first card ，reboot the windows virtual os, then this problem 
+happened !
+
+
+
+
+we found that the sencond network card will  replace the first one , then the 
+ip address of "network connection 2 " become 192.168.1.1 。
+
+
+Our third party users began to complain about this bug 。All the business of the 
+second ip  lost !!! 
+
+I mean both of windows and linux has this bug ,  we solve this bug in linux  
+throught bonding netcrad pci and mac address 。
+
+There is no good solution on windows os . thera are ?  we implemented a plan to 
+resumption of IP by QGA.  Is there a better way ?
