Public bug reported:
qeum version:
QEMU emulator version 4.2.1
I met a problem when I tried to use IVSHMEM. Command lspci does not show the IVSHMEM device.
Below is the configuration from my side:
1. guest vm xml configuration.

<size unit='M'>2</size>
<address type='pci' domain='0x0000' bus='0x00' slot='0x10' function='0x0'/>
</shmem>
2. after the booting up and I found the qemu commandline ideedly have the device option:
ps aux | grep ivshmem
/usr/bin/qemu-system-x86_64
.......(ignore other options)

Hi ChangLimin,
Thanks for your reply. I checked again to find the device... I thought the
name was ivshmem.
I don't find any driver code for IVSHMEM in the linux and qemu repo. Can
you give me some help?

There is no driver for it. You should write it by youself. Maybe you can refer to
http://doc.dpdk.org/guides-1.8/prog_guide/ivshmem_lib.html and dpdk source.
Gool luck!

Hi ChangLimin,
Thanks for your reply. I checked again to find the device... I thought the name was ivshmem.
I don't find any driver code for IVSHMEM in the linux and qemu repo. Can you give me some help?

Title:
command lspci does not show the IVSHMEM device
Status in QEMU:
Invalid
Bug description:
qeum version:
QEMU emulator version 4.2.1
I met a problem when I tried to use IVSHMEM. Command lspci does not show the IVSHMEM device.
Below is the configuration from my side:
1. guest vm xml configuration.
<shmem name='ivshmem'>
<model type='ivshmem-plain'/>
<size unit='M'>2</size>
<address type='pci' domain='0x0000' bus='0x00' slot='0x10' function='0x0'/>
</shmem>
2. after the booting up and I found the qemu commandline ideedly have the device option:
ps aux | grep ivshmem
/usr/bin/qemu-system-x86_64
.......(ignore other options)
-object memory-backend-file,id=shmmem-shmem0,mem-path=/dev/shm/hostmem,size=4194304,share=yes -device ivshmem-plain,id=shmem0,memdev=shmmem-shmem0,bus=pcie.0,addr=0x10
