KVM is an open source virtualization solution in a kernel module. KVM can virtualize x86, PowerPC, and S390 guests.
Installing KVM
It is possible to install just qemu and libvirt for local management, but most users will probably want libvirt-deamon and/or virt-manager for a GUI.
sudo apk add qemu-system-x86_64 libvirt sudo apk add libvirt-daemon dbus polkit
Enable the KVM kernel module
sudo modprobe kvm-intel
or
sudo modprobe kvm-amd
Add your user to the follwing groups so you can mange the vms
sudo addgroup user kvm sudo addgroup user qemu sudo addgroup user libvirt
Set libvirtd and dbus to start on startup
sudo rc-update add libvirtd sudo rc-update add dbus
Configure PolicyKit
In order to use libvirtd to remotely control KVM over ssh PolicyKit needs a .pkla informing it that this is allowed. Write the following file to /etc/polkit-1/localauthority/50-local.d/50-libvirt-ssh-remote-access-policy.pkla
