KVM (Kernel-based Virtual Machine) is a full virtualization solution
for Linux on x86 hardware containing virtualization extensions
(Intel VT or AMD-V). KVM is divided into the KVM-KMOD package
(kernel modules) and the QEMU-KVM package (slightly modified QEMU)
which are both available as separate Slackbuilds.
KVM-KMOD consists of a kernel module, 'kvm.ko', that provides the
core virtualization infrastructure and a processor specific module,
'kvm-intel.ko' or 'kvm-amd.ko'. Slackware provides these modules
in the 'a/kernel-modules*' packages. In most cases, the provided
versions are sufficient to run QEMU-KVM. KVM-KMOD is only needed
if you want to change the KVM modules to a different version.
KVM-KMOD updates the modules without overwriting the ones provided
by Slackware. If you uninstall KVM-KMOD, you will need to run
'depmod -a' to regenerate the modules.dep and map files to regain
access to the Slackware provided versions.
By default, this script uses the "users" group for determining who
has permission to use /dev/kvm, but if you prefer something else,
set KVMGROUP when running the script, e.g.:
KVMGROUP=wheel sh kvm-kmod.SlackBuild
