+
+==== Description
+
+This project aims to implement a man:vmm[4] accelerator backend for QEMU.
+By interfacing QEMU with FreeBSD's native hypervisor infrastructure, users can run virtual machines with near-native performance using hardware virtualization extensions (VMX/SVM), similar to how KVM functions on Linux.
+This combines the extensive device emulation ecosystem of QEMU with the performance of the FreeBSD kernel hypervisor.
+
+==== Status
+
+The backend is now functional enough to boot a FreeBSD guest using a single vCPU.
+The core infrastructure for interfacing QEMU with `libvmmapi` is in place.
+Crucially, interrupt controllers (8259 PIC, IOAPIC, LAPIC) are now successfully utilizing the kernel's `vmm` implementations rather than userspace emulation.
+
+==== Open Items & Call for Help
+
+While the heavy lifting is complete, there are key areas where community contributions would be highly valued to get this merged upstream:
+
+- Guest SMP Support: Currently, the guest is limited to 1 vCPU.
+  We are looking for assistance in debugging the existing loop/thread handling in the backend to enable multi-CPU support.
+- Device Offloading: The RTC and HPET timers are currently still emulated in userspace by QEMU.
+  These need to be reworked to use the `vmm` in-kernel versions for better performance and correctness.
+- General Stability: As with any hypervisor backend, we need help with edge-case testing and stress testing across different guest OS types.
+
+I would like to thank Google for the sponsorship, and the FreeBSD Project for the mentorship and opportunity to contribute to the system.
