10.4. Paravirtualization providers
VirtualBox allows exposing a paravirtualization interface to facilitate accurate and efficient execution of software within a virtual machine. These interfaces require the guest operating system to recognize their presence and make use of them in order to leverage the benefits of communicating with the VirtualBox hypervisor.

Most mainstream, modern operating systems, including Windows and Linux, ship with support for one or more paravirtualization interfaces. Hence, there is typically no need to install additional software in the guest (including VirtualBox Guest Additions) to make use of this feature.

VirtualBox provides the following interfaces:

Minimal: Announces the presence of a virtualized environment. Additionally, reports the TSC and APIC frequency to the guest operating system. This provider is mandatory for running any Mac OS X guests.

KVM: Presents a Linux KVM hypervisor interface which is recognized by Linux kernels starting with version 2.6.25. VirtualBox's implementation currently supports paravirtualized clocks and SMP spinlocks. This provider is recommended for Linux guests.

Hyper-V: Presents a Microsoft Hyper-V hypervisor interface which is recognized by Windows 7 and newer operating systems. VirtualBox's implementation currently supports paravirtualized clocks, APIC frequency reporting and relaxed timer checks. This provider is recommended for Windows and FreeBSD guests.

用百度翻译过来就是Windows的来宾系统就用Hyper-V会好一些了
