-[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.
