qemu-user 1.0-2011.12-0ubuntu1 (i386 binary) in ubuntu precise

 QEMU is a fast processor emulator: currently the package supports
 ARM, CRIS, i386, M68k (ColdFire), MicroBlaze, MIPS, PowerPC, SH4,
 SPARC and x86-64 emulation. By using dynamic translation it achieves
 reasonable speed while being easy to port on new host CPUs.
 .
 This package provides the user mode emulation binaries for targets other
 than x86 and x86-64. In this mode QEMU can launch Linux processes compiled
 for one CPU on another CPU.
