You seem to already know which APIs go with which guests.

What is paravirtualization interface virtualbox. Is there documentation on how to set the acceleration settings via the Vagrantfile. Oracle VM VirtualBox enables the exposure of a paravirtualization interface to facilitate accurate and efficient execution of software within a virtual machine. For example VirtualBox provides virtio network interface which entirely eliminates emulating network cards in.

Paravirtualization means that the guest is aware of the virtualized environment and utilizes certain APIs provided by host and hypervisor to improve performance. Paravirtualization is a type of virtualization in which a guest operating system OS is recompiled installed inside a virtual machine VM and operated on top of a hypervisor program running on the host OS. This channel is the Paravirtualization interface.

Paravirtualization PV is an enhancement of virtualization technology in which a guest operating system guest OS is modified prior to installation inside a virtual machine VM in order to allow all guest OS within the system to share resources and successfully collaborate rather than attempt to emulate an entire hardware environment. 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 Oracle VM VirtualBox hypervisor. There is little point in providing the guest OS with an API it doesnt understand.

The paravirtualization API allows the guest to talk to the hypervisor. Updated hypervisors like Virtualbox can present a communications channel between the guest OS and Virtualbox to help the guest OS run better when it knows its in a virtual machine. Oracle VM VirtualBox enables the exposure of a paravirtualization interface to facilitate accurate and efficient execution of software within a virtual machine.

VirtualBoxs implementation currently supports paravirtualized clocks and SMP spinlocks. Presents a Microsoft Hyper-V hypervisor interface which is recognized by Windows 7 and newer operating systems. This provider is recommended for Linux guests.

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 Oracle VM VirtualBox hypervisor. In comparison to traditional full virtualization paravirtualization can cut down on overhead and improve system performance. Presents a Microsoft Hyper-V hypervisor interface which is recognized by Windows 7 and newer operating systems.

The options available are documented under the –paravirtprovider option in Section 78 VBoxManage modifyvm. This provider is recommended for Linux guests. Is there a way to set this option in a Vagrantfile.

VirtualBoxs implementation currently supports paravirtualized clocks APIC frequency reporting guest debugging guest crash reporting. VirtualBox 5 exposes a setting called Paravirtualization Interface that can improve performance for some specific guest operating systems. Oracle VM VirtualBox provides paravirtualization interfaces to improve time-keeping accuracy and performance of guest OSes.

Modern Windows expects to communicate to the hypervisor via the Hyper-V protocol. A paravirtualization interface provides admins with additional capabilities beyond full virtualization such as easier backups faster migrations improved system.
