A KVM backend for VirtualBox that replaces VirtualBox's own hypervisor with the Linux kernel's KVM. It lets users run their existing VirtualBox VMs on top of KVM, enabling coexistence with QEMU/KVM workloads and removing the need for the vboxdrv kernel driver.

Use cases

• run VirtualBox VMs alongside QEMU/KVM VMs on the same Linux host
• avoid installing the VirtualBox kernel driver (vboxdrv)
• use KVM hardware virtualization features like APICv with VirtualBox VMs
• enable the VirtualBox KVM backend on NixOS via configuration
• migrate existing VirtualBox guest VMs to a KVM-based hypervisor

When to choose

• you are on Linux and want VirtualBox's UI/workflow backed by KVM
• you already run QEMU/KVM VMs and want VirtualBox VMs to coexist without driver conflicts
• you use NixOS and want a one-line configuration switch to the KVM backend

When to avoid

• you need identical guest performance characteristics to stock VirtualBox
• you are not on Linux, since KVM is Linux-only
• you need prebuilt packages for your distribution and cannot build from source or find a community package
