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 all emulation targets for qemu; if you
|
|
prefer to build specific target(s), do this:
|
|
|
|
TARGETS=arm-softmmu,arm-linux-user,armeb-linux-user ./qemu.SlackBuild
|
|
|
|
(Refer to qemu documentation for available emulation targets.)
|
|
|
|
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 (to access iSCSI targets directly), libslirp (user mode
|
|
networking), libcacard, spice, usbredir, virglrenderer, libnfs, snappy,
|
|
glusterfs, and vde2, numactl. sphinx-rtd-theme and Sphinx (to build
|
|
documentation) are optional dependencies that will be automatically
|
|
detected during compilation, if present (all avialable on SBo).
|
|
|
|
To enable user mode networking, install libslirp, then compile qemu:
|
|
|
|
SLIRP=yes ./qemu.SlackBuild
|
|
|
|
NOTES:
|
|
This version breaks some backward compatibility with earlier versions.
|
|
Consult the official changelogs for details.
|
|
|
|
If there are problems after upgrading with missing or wrong versioned
|
|
libraries please try uninstalling any previous versions before
|
|
rebuilding a new one.
