No image in looking-glass client

Software & Operating Systems Looking Glass
1

Hi,

I have set up a Windows 10 guest on an Arch Linux host.

My problem is that I can’t see any image in the client, but I don’t get an error message either.

What I have done:

  • Windows 10 guest started with virsh
  • Connect with virt-viewer
  • Log in and start “looking-glass-host.exe” as admin (there is no response)
  • start looking-glass-client on the host -> virt-viewer terminates itself in this moment
  • Only the looking-glass logo appears.

Keyboard entries are successfully sent to the guest.

/dev/shm/looking-glass is 32 MB, seems to work.

looking-glass-client -k shows UPS: 0 FPS: 120

Output of looking-glass-client

When I run “tasklist” on the Windows command line as admin, there is no looking-glass-host.exe. Is this correct?

When I start “virt-viewer” again, the looking-glass-client terminates. Seems like they know about each other. :slight_smile:

Does anyone have an idea where I can look for the error?
Thanks!

You must not have a virtual video device attached, the host application can not function with it.

I am facing the exact same issue.
Running Manjaro with a 5700 XT has a host GPU and a Vega 64 as a Guest GPU the only thing I see is the looking glass logo when starting the client. Video is set from QXL to none.
It seems like looking glass host in Windows and Client on Linux do nto communicate with each other but I think I followed all the steps :frowning:

No you are not, something is messing with your SPICE connection to the guest.
