Thanks for the quick reply.
What we are building is a Qt application that can visualize disk fragmentation data.
We are collecting the fragmentation data by calling `filefrag` on files from some partition, and the outputs will be directed into a log file. The Qt app simply reads that file and parse it.
Here is how I do it in qemu:
1. Login as root
2. Run a python script to run `filefrag` on files and creates a log file somewhere. (also not sure where should I put this file?)
3. The Qt app will try to open the log file and read it.
Instead of preparing the log file and read it from Qt app, I also tried to run the `filefrag` command inside the Qt app with QProcess, but it has a similar SMACK error.

Hope this is enough information for you.Thanks
