Bhyve


bhyve is a type-2 hypervisor initially written for FreeBSD. It can also be used on a number of illumos based distributions including SmartOS, OpenIndiana, and OmniOS. A port of bhyve to macOS called xhyve is also available.

Features

bhyve supports the virtualization of several guest operating systems, including FreeBSD 9+, OpenBSD, NetBSD, Linux, illumos, DragonFly and Windows NT. bhyve also supports UEFI installations and VirtIO emulated interfaces. Windows virtual machines require VirtIO drivers for a stable operation. 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 USB controllers, NVM Express controllers, High Definition Audio Controllers, raw framebuffer device attached to VNC server, and AHCI/PCI Passthrough.
Since the support for peripherals is incomplete, hardware-accelerated graphics is only available using PCI passthrough. But, Intel GVT should allow sharing the device with the host.
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.
