Bhyve
BSD Hypervisor
From Wikipedia, the free encyclopedia
bhyve (pronounced "bee hive", formerly written as BHyVe for "BSD hypervisor") is a type-2 (hosted) hypervisor initially written for FreeBSD.[1][2][3] It can also be used on a number of illumos based distributions including SmartOS,[4] OpenIndiana, and OmniOS.[5] A port of bhyve to macOS called xhyve is also available.[6]

Features
bhyve supports the virtualization of several guest operating systems, including FreeBSD 9+, OpenBSD, NetBSD, Linux, illumos, DragonFly and Windows NT[7] (Windows Vista and later, Windows Server 2008 and later). bhyve also supports UEFI installations and VirtIO emulated interfaces. Windows virtual machines require VirtIO drivers for a stable operation.[citation needed] Current development efforts aim at widening support for other operating systems for the x86-64 architecture.
Support for peripherals relies on basic and VirtIO drivers and supports: eXtensible Host Controller Interface (xHCI) USB controllers, NVM Express (NVMe) controllers, High Definition Audio Controllers, raw framebuffer device attached to VNC server (Video Output), and AHCI/PCI Passthrough.[8]
Since the support for peripherals is incomplete, hardware-accelerated graphics is only available using PCI passthrough. But, Intel GVT (and other vGPUs with driver support) should allow sharing the device with the host.[9]
bhyve performs about the same as its competitors with lack of memory ballooning and accelerated graphics interface, but bhyve has a more modern codebase and uses fewer resources. In the case of FreeBSD the resource management is more efficient. FreeBSD is also known for its exemplary I/O speeds; running bhyve from FreeBSD has a lot of advantages for time-critical virtual appliances by reducing I/O time, especially on disk and network related loads.
Applications
- Docker on macOS uses a bhyve derivative called HyperKit. It is derived from xhyve, a port of bhyve to macOS's Hypervisor framework.[10]
- iohyve on FreeBSD is a command-line utility to create, store, manage, and launch bhyve guests using built in FreeBSD features.[11]
- vm-bhyve on FreeBSD is a shell-based, bhyve manager with minimal dependencies.[12]
- BVCP on FreeBSD is a lightweight, native, full featured web interface for managing virtual machines.[13]
- FreeNAS, based on FreeBSD, uses bhyve alongside its file sharing services to provide hosting for VMs.[14]
Other distributions
- ClonOS, a FreeBSD-based distribution for virtual hosting platform and appliance, primarily uses bhyve and has a web-based management interface.[15]
- MyBee, a FreeBSD-based distribution for managing cloud VMs (bhyve) through a simplified API.[16]
- SmartOS, an Illumos-based distribution for managing cloud VMs (bhyve, Solaris zones) through a simplified API.
- MidnightBSD, a desktop operating system, includes bhyve.[17]
