I am following the guide exactly, however in device manager in windows I don’t see any “PCI standard RAM Controller” that are at a matching bus and I can’t find any devices without a driver either.
Why have you specified the PCI address? Not sure if this is the cause as I no longer use libvirt myself but you say you followed the guide exactly, and this is not part of the guide.
<address type='pci' domain='0x0000' bus='0x08' slot='0x01' function='0x0'/>libvirt sometimes adds information.
From my working VM:
<shmem name='looking-glass'>
<model type='ivshmem-plain'/>
<size unit='M'>128</size>
<address type='pci' domain='0x0000' bus='0x02' slot='0x02' function='0x0'/>
</shmem>
I’m still adding it using QEMU cmdline args in my domain XML and it works fine.
<qemu:commandline>
<qemu:arg value='-device'/>
<qemu:arg value='ivshmem-plain,memdev=ivshmem'/>
<qemu:arg value='-object'/>
<qemu:arg value='memory-backend-file,id=ivshmem,share=on,mem-path=/dev/shm/looking-glass,size=64M'/>
</qemu:commandline>I did not specify the address, it was assigned automatically.
Finally figured it out! The problem was that that I was searching for a device without drivers, however windows did not display the device as an unknown device. Now I however ran into a new problem: after starting the client on host I am only presented with this:
this is the output of the client:
[I] main.c:777 | run | Looking Glass (a12-13-g473e4716fc)

EDIT:
So after further testing this is what actually made it work.
It is wierd though that it appears in the same bus as the membaloon device:

UPDATE:
it works, but only when an RDP session is active.
Do you have a display attached to the VM?
Yes, I have the monitor plugged into my second GPU with HDMI. I’ll get a second keyboard and try to run the host manually if something went wrong there.
Check if the display is outputting.
Looking glass requires a display. Whether it be a dummy plug or an actual display, it doesn’t matter.
Found out something new: if I remove the SPICE and QXL devices from the VM and run the client with the -s option it works!
Yeah, that’d do it.
I am seeing picture if I switch the input on the monitor.
How can I setup spice without the QXL graphics? Or is that not recommended?
I forget what my configuration is and i am not at my workstation at the moment.
You should just be able to create a channel of type spice, set it to run on a port and you’re good.
Thanks!
Everything works now. Could you just send me your spice setup when you get the chance? Thanks again for all the support from everyone!
If you want to use libvirt it will continue to place the video device in there. Disabling it in device manager inside the VM is sufficient for the looking glass host to work appropriately. If you move to qemu directly for the VM you do not have to have a video device.
Me personally I just disable the device in device manager, as its simpler for me managing multiple machines through libvirt.

and you do have a monitor or dummy plug attached?
When I tried to run a game in fullscreen or borderless fullscreen I get a [stream paused] for about one second. After this is gone I can see my mouse moving again but the rest of the screen is frozen. I restarted the client but now I have a black screen but can still see my mouse.
Is there any way to solve cursor getting misaligned? I switch between looking glass frequently and it often become unaligned for various reasons. It is quite annoying…
