After I sent the mail, I checked with a simple project created with Qt
Creator. The makefile generated by QMake has 'mtune=atom' in it. But I
don't see any reason for that to happen. So the problem is not with Qt
Creator sources. Any makefile generated with QMake will probably have this.
I'm running the VM on core i5 processors and output of "g++ -Q -v" when
run on simple cpp files is as expected. I've sent a mail to Fedora KDE
mailing list to see if this has something to do with the way Qt RPMs
were compiled. Could it be that?
I'm attaching /proc/cpuinfo and output of "g++ -Q -v" for reference.

Oops.. Sorry about that oversight.
Thanks,
