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-kvm 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.
qemu-kvm code has been merged back into qemu since version 1.3.0.
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
We patch the installed udev rules to require membership in "users"
group instead of a custom "kvm" group to uses /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-x86_64 with kvm enabled.
spice and usbredir are optional dependencies.
