To check a few things:<br>
<br>
* Is lttng-sessiond being run by the root user?<br>
* If you run lttng-session with the "-vvv" option, are there messages <br>
related to loading the kernel modules?<br>
* Once the lttng-sessiond is started, you can check to see if the <br>
kernel modules have been loaded by running the following command:<br>
<br>
```<br>
lsmod | grep lttng<br>
```<br>
<br>
thanks,<br>
