bhyve is a hypervisor that runs on the FreeBSD/amd64 + platform. At present, it runs FreeBSD (8.x or later), Linux + i386/x64, OpenBSD i386/amd64, and NetBSD/amd64 guests. Current + development is focused on enabling additional guest operating + systems and implementing features found in other hypervisors.

+ +

Peter Grehan did a status update at bhyvecon 2015 in + Tokyo. The slides are available at + http://bhyvecon.org/bhyvecon2015-Peter.pdf

+ +

Mihai Carabas presented the results of his GSoC project + on implementing instruction caching in bhyve at AsiaBSDCon + 2015 in Tokyo. The slides are available at + http://people.freebsd.org/~neel/bhyve/bhyve-cache-emul-slides.pdf

+ +

A number of improvements were made to bhyve this quarter:

+ +

The RTC device model can now be instructed to keep UTC time + instead of localtime. This is useful for guests like OpenBSD + that expect the RTC to keep UTC time.
The virtio-blk device now does I/O asynchronously without + blocking the vcpu thread that initiated the I/O.
The virtio-blk and ahci-hd devices are now able to execute + multiple I/O requests in parallel. This can significantly + boost virtual disk throughput.
The ahci-hd device emulation advertises TRIM to the guest + if the backend device supports it (e.g., ZVOL).
The virtio-blk and ahci-hd devices now advertise the proper + logical and physical block size of the backend device or file.

+ + + + + +

Improve documentation.

+ + + +

bhyveucl is a script for starting bhyve instances based on a + libUCL config file. More information is at + https://github.com/allanjude/bhyveucl

+ + + +

Add support for virtio-scsi.

+ + + +

Flexible networking backends: wanproxy, vhost-net.

+ + + +

Move to a single process model, instead of bhyveload + and bhyve.

+ + + +

Support running bhyve as non-root.

+ + + +

Add filters for popular VM file formats (VMDK, VHD, + QCOW2).

+ + + +

Implement an abstraction layer for video (no X11 or SDL in + the base system).

+ + + +

Suspend/resume support.

+ + + +

Live Migration.

+ + + +

Nested VT-x support (bhyve in bhyve).

+ + + +

Support for other architectures (ARM, MIPS, PPC).
