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. +qemu-kvm is a generic and open source virtualizer. qemu-kvm achieves +near native performances by leveraging the kvm-kmod modules and +executing the guest code directly on the host CPU.

For those system guest types that don't utilize +the kvm-kmod modules, it is recommended to use the qemu package instead +of this qemu-kvm package. -QEMU-KVM requires a system group and uses 'kvm' as the default. If you -want to use a different group like 'users' then run the script like this: -KVMGROUP=users sh qemu-kvm.SlackBuild +The qemu-kvm SlackBuild renames the primary binary from 'qemu-system- +x86_64' to 'qemu-kvm' so that the qemu SlackBuild won't overwrite it +if both packages are installed on the same host system. The qemu-kvm +SlackBuild patches the installed udev rules so that you no longer are +required to use the system group 'kvm' as the default. The 'users' +group is set as the default in this SlackBuild. If you want to use a +different group, then run the SlackBuild like this: + KVMGROUP=group sh qemu-kvm.SlackBuild -After package installation, make sure you have the KVMGROUP present on -your system and that all desired users are members of that group. -Don't forget to load the KVM-INTEL or KVM-AMD module depending on your -processor. - -The script builds only x86 and x86_64 Linux Target CPU emulators by default. -If you need to emulate all target CPUs, set BUILD_ARCH to "all" but be -aware that the compilation will take a lot longer, and you should really -be using plain "qemu" for the others (since they can't use the KVM stuff -anyway.
