# GUI Troubleshooting
|
||||
|
||||
If you can start your VM, but can't launch any applications, then you need to fix the issues from the `VM console`, accessible from xen through:
|
||||
|
||||
~~~
|
||||
qvm-start <VMname> # Make sure the VM is started
|
||||
sudo xl console <VMname>
|
||||
~~~
|
||||
|
||||
## Tips
|
||||
|
||||
### Disable auditd messages
|
||||
|
||||
To disable auditd messages, you need to edit your VM kernel parameters:
|
||||
|
||||
~~~
|
||||
previous_kernel_parameters=$(qvm-prefs --get <VMname> kernelopts) # Get current kernel parameters
|
||||
qvm-prefs --set <VMname> kernelopts "<previous_kernel_parameters> audit=0"
|
||||
~~~
|
||||
|
||||
Then, restart your VM.
|
||||
|
||||
Once your troubleshooting is done, don't forget to remove this kernel parameters, it makes troubleshooting VMs not starting easier.
