The Console tab provides convenient access to the virtual device’s console. You can use the Console to quickly see system and kernel logs (including SELinux violations), and to quickly run commands without needing to connect over ADB or SSH.
The console can sometimes be flooded with system and kernel logs, making it difficult to use interactively. If you’re using the console interactively, you may want to run dmesg -n 1 to prevent all messages, except emergency (panic) messages. Run dmesg -n 4 to restore the default behavior, and run dmesg -n 7 to log all messages to the console.
You can also view the device console in your own console application, using the Console Link from the Connect tab.
