19.3. SPICE Log Files
SPICE log files are useful when troubleshooting SPICE connection issues. To start SPICE debugging, change the log level to debugging. Then, identify the log location.
Both the clients used to access the guest machines and the guest machines themselves have SPICE log files. For client-side logs, if a SPICE client was launched using the native client, for which a console.vv file is downloaded, use the remote-viewer command to enable debugging and generate log output.

19.3.3. SPICE Logs for SPICE Clients Launched Using console.vv Files
For Linux client machines:
Enable SPICE debugging by running the
remote-viewercommand with the--spice-debugoption. When prompted, enter the connection URL, for example, spice://virtual_machine_IP:port.# remote-viewer --spice-debug
To run SPICE client with the debug parameter and to pass a .vv file to it, download the console.vv file and run the
remote-viewercommand with the--spice-debugoption and specify the full path to the console.vv file.# remote-viewer --spice-debug /path/to/console.vv
For Windows client machines:
-
In versions of
virt-viewer2.0-11.el7ev and later, virt-viewer.msi installsvirt-vieweranddebug-viewer.exe. Run the
remote-viewercommand with thespice-debugargument and direct the command at the path to the console:remote-viewer --spice-debug path\to\console.vv-
To view logs, connect to the virtual machine, and you will see a command prompt running GDB that prints standard output and standard error of
remote-viewer.
