Yes, I had this problem too. U only compiled the program using the 
'user' parameters. But to get the virtualisation going, you need to 
compile at least one 'softmmu' (whatever that is). Doing that will 
create the executable: qemu    (this is the executable you want :)   )

So I run Linux and I compile it with (and I really need it):

i386-linux-user AND i386-softmmu     (i386 can be replaced with your 
arch such as: ppc, sparc, x86_64, mips, mipsel and arm)

That should create an executable called qemu (as stated before) which 
should not segfault immediatly lol :)

                                             Good Luck :)
