Binary package “qemu-kvm-extras” in ubuntu precise

QEMU system and user mode emulation (transitional package)

 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 is a transitional package depending on the system and user mode
 emulation binaries. You can remove it once the upgrade is complete and
 nothing depends on it.
