     "Virtualization for Linux on x86 hardware containing virtualization extensions")
    (description
     "KVM (for Kernel-based Virtual Machine) is a full virtualization solution
for Linux on x86 hardware containing virtualization extensions (Intel VT or
AMD-V).  It consists of a loadable kernel module, kvm.ko, that provides the
core virtualization infrastructure and a processor specific module,
kvm-intel.ko or kvm-amd.ko. KVM also requires a modified QEMU although work is
underway to get the required changes upstream.")
