qemu-user-static 1.0.50-2012.01-0ubuntu2 (amd64 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, built
 statically. In this mode QEMU can launch Linux processes compiled for
 one CPU on another CPU.
