QEMU is a generic and open source machine emulator and virtualizer.

When used as a machine emulator, QEMU can run OSes and programs made for 
one machine (e.g. an ARM board) on a different machine (e.g. your own PC). 
By using dynamic translation, it achieves very good performances.

qemu (with kvm enabled) achieves near native performances by leveraging 
the kvm-kmod modules and executing the guest code directly on the host 
CPU.  Slackware provides pre-built 32/64 bit x86 kvm-kmod modules or you 
can build different versions with the kvm-kmod package.

By default, this script builds only the x86 and arm emulation targets
for qemu; if you prefer to build all supported targets, do this:

  TARGETS=all ./qemu.SlackBuild

Disable vnc support via:

  VNC_ENABLE=no ./qemu.SlackBuild

Audio drivers support defaults to "alsa,oss,sdl" and can be adusted via

AUDIODRIVERS="alsa,oss" ./qemu.SlackBuild

We patch the installed udev rules to require membership in "users" 
group instead of a custom "kvm" group to use /dev/kvm.  If you prefer
something different, then run the build script like this:
  
  KVMGROUP=group ./qemu.SlackBuild

Don't forget to load the 'kvm-intel' or 'kvm-amd' module (depending on 
your processor) prior to launching qemu-system-ARCH with kvm enabled.
For older/unmaintained qemu frontends, this build also creates a symlink
to qemu-system-ARCH at /usr/bin/qemu-kvm.

spice, usbredir, and device-tree-compiler are optional dependencies.
If you wish to emulate ARM, you will want device-tree-compiler.

NOTES:
  This version breaks some backward compatibility with earlier versions.
  Consult the official changelogs for details.

  Slackware's libusb is too old. Thus, to enable usb redirection, install
  usbredir, download libusb-1.19, and build with LIBUSB=yes ./qemu.SlackBuild
