It was very strange. The commits were "counting" but there was no 
obvious result, most of the time.
Sometimes it starts and works OK, and sometimes I couldn't even execute 
a command.
Anyway, what I did is erase _everything_ from the hard-disk that had a 
substring "xen" in the file or directory name.
Then, I installed xen 3.1 from the website, kernel from the website, new 
ptlsim, etc.
And now it works.
