slackbuilds/qemu/build

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 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 "pa,alsa,oss,sdl" and can be adusted

by running the build script like this:



  AUDIODRIVERS="pa,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



To have the qemu-bridge-helper installed setuid root, allowing regular

users to use extended networking capabilities, do this:



  BRIDGE_HELPER_SETUID=yes ./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.



libiscsi, libcacard, spice, usbredir, virglrenderer,

device-tree-compiler, libnfs, snappy, glusterfs and vde2 are optional

dependencies.



NOTE:

To compile with virglrenderer, you will need to upgrade to

mesa-12.0.0 or higher.



Sphinx is optional but required in order for any of the documentation to be

built. 



libseccomp (to use libvirt) and libiscsi (to access iSCSI targets

directly) are optional dependencies, and will be picked up, if

present, during the compilation.



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.



  SDL 1.2 support is deprecated, SDL 2.0 should be used instead.

  Python 3.x can be used to build QEMU.
