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-viewer
command with the--spice-debug
option. 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-viewer
command with the--spice-debug
option 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-viewer
2.0-11.el7ev and later, virt-viewer.msi installsvirt-viewer
anddebug-viewer.exe
. Run the
remote-viewer
command with thespice-debug
argument 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
.
