qemu can be run for a variety of cpu targets and in multiple modes so 
just using the name 'qemu' for the i386 full emulation binary is 
inconsistent with the rest of the binary names and a little ambiguous. 
what you are probably looking for is either qemu-system-x86_64 or 
qemu-system-i386. those are the binaries for qemu running in 
full-emulation mode for 64 bit and 32 bit x86 systems, respectively. 
just qemu-x86_64 would be for running 64 bit x86 user emulation mode. 
for other cpu architectures, replace the architecture on the end of the 
binary name with the architecture you need.

this change was made for the 1.0 release which came out at the end of 
last year and there is a note about it in the changelog. 
http://wiki.qemu.org/ChangeLog/1.0 maybe there will be a new binary in 
the future that is more of a management tool or a wrapper around the 
various binaries but as far as i know this work has not started.
