Unable to find IVSHMEM device, terminating service

Software & Operating Systems Looking Glass
1

Hi,
I’ve been following the installation instructions , but I guess I messed up something because i get the subject error in the host log file. the host app exits immediately upon running.
In the windows device manager I see a “IVSHMEM device” under “System devices”. when I try to update the driver with the driver in the host app folder windows says that I already have the latest version of the driver installed.
Any idea why the host app cannot find the driver?
Thanks

If you installed version B6, which is the currently stable version, the installer will also install the IVSHMEM driver so there’s no need to separately install it. The later entries on the service log you posted (after 4:53) indicate the service starts successfully. If you need further assistance, please post the host application log (not the service log). Please post the full log in text format, not screen captures.

Thank you guys for your help.
I’m using the B6 version.
I’m attaching both log files in text format.
suddenly I cant post links. please add “://” “.” and “/”:

So I see my video driver in windows is Microsoft Basic Render Driver, even though I pci-passthrough my NVIDIA card.
Any idea what to use for display and vga?
Thanks.

Here is my qemu invocation:

sudo chown $USER /dev/vfio/11
qemu-system-x86_64 --enable-kvm -smp cpus=4 -cpu host -m 8G \
-mem-prealloc \
-drive file=windows-disk.qcow2,media=disk \

I assume it’s the way I configured my display.
This docs/B6/install/#keyboard-mouse-display-audio page says:

  • Find your <video> device, and set <model type='vga'/>
  • If you can’t find it, make sure you have a <graphics> device, save and edit again.

Do you know how do these translate to qemu parameters?
Thanks.
