summary

A minimal FreeBSD hypervisor originally written 2011 and upstreamed later, bhyve runs as a UNIX process with vCPUs as threads, uses a kernel module + character device + lib + bhyve process and bhyvecontrol, and requires CPUs with EPT (second-level page tables) (Nehalem+). Initial tree supported up to eight vCPUs, paravirtual I/O, and boot via UEFI; today it offers PCI pass-through, a built‑in VNC framebuffer, demand‑paged guest memory, broad BSD/Linux guest support and limited recent Windows 64‑bit support. Lacks nested virtualization, GUI front end, GPU passthrough and live migration.
