-reproduce = """1. add new pci-bridge into windows vm, add windows vm xml configuration like this:
-```xml
-<devices>
-  <controller type='pci' index='0' model='pci-root'/>
-  <controller type='pci' index='1' model='pci-bridge'>
-    <address type='pci' domain='0' bus='0' slot='0x0d' function='0' multifunction='off'/>
-  </controller>
-</devices>
-```
-
-2.restart this Windows vm, new pci-bridge has been created, its name is pci.1 and bus is bus.1:
-```sh
-$ virsh qemu-monitor-command --hmp --domain 56 --cmd info pci
-  Bus  0, device  13, function 0:
-    PCI bridge: PCI device 1b36:0001
-      IRQ 10.
-      BUS 0.
-      secondary bus 1.
-      subordinate bus 1.
-      IO range [0xc000, 0xcfff]
-      memory range [0xfe000000, 0xfe1fffff]
-      prefetchable memory range [0xe4000000, 0xe41fffff]
-      BAR0: 64 bit memory at 0xfe422000 [0xfe4220ff].
-      id "pci.1"
-```
-3. create a shm file `/dev/shm/test1` in host using `shm_open()`, size is 32M
-
-4. create new object: 
-```sh
-virsh qemu-monitor-command --hmp --domain 56 --cmd object_add memory-backend-file,share=on,id=objtest1,size=32M,mem-path=/dev/shm/test1
-```
-
-5. insert this ivshmem file into new pci-bridge and use bus.1 slot number(1:1.0):
-```sh
-virsh qemu-monitor-command --hmp --domain 56 --cmd device_add ivshmem-plain,memdev=objtest1,id=test1,bus=pci.1,addr=0x01.0x00
-```
-
-6. After inserting this ivshmem file into new pci-bridge, the remote desktop connection of this windows vm disconnects.
-
-7. New ivshmem file has been created:
-```
-$ virsh qemu-monitor-command --hmp --domain 57 --cmd info pci
-  Bus  1, device   1, function 0:
-    RAM controller: PCI device 1af4:1110

-The newly added ivshmem device can be found in the device manager of the Windows vm, but sometimes it cannot be found.

-Thanks for your help!"""
