It depends on how you have launched your qemu instance. If you have used 
user mode networking, the guest IP will always be 10.0.2.15. There's 
plenty of documentation about qemu networking. Start from the man page 
and the built-in documentation (usually 
/usr/share/doc/qemu/system/net.html on a Linux host).
