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.
