Re: Fwd: Call for Foundation-supported Project Ideas

Hello, all,

Thank you, Matthew, for your description.

As Matthew said, any feedback or any help in bringing these things
upstream is highly appreciated. I want to add links to repo, wiki and
reviews for a better view of our projects.

In UPB (University Politehnica of Bucharest), we work on various bhyve
related projects (some of them are research projects, other are
faculty projects). For better awareness, here is our wiki page [1]
where we present the ongoing projects, reviews, tutorials or other
resources for them.

We have a GitHub [2] organisation where you can find our main tracks:
- improvements to FreeBSD (mainly bhyve) - a forked repository from
FreeBSD/freebsd-src. Usually, each project has a branch where we
develop things and the main branch is used only for synchronisation
with the FreeBSD/freebsd-src main repository.
- improvements to libvdsk - a standalone library that brings support
for different types of file formats that may be used for bhyve (raw,
qcow2, vmdk).

We have pending reviews on Phabricator for which we need feedback:
- bhyve - ARMv8 implementation - https://reviews.freebsd.org/D26976
- bhyve - Snapshot Save and Restore - multiple devices
https://reviews.freebsd.org/D26387
- Warm Migration feature for bhyve - https://reviews.freebsd.org/D28270
- bhyve - JSON format snapshot - https://reviews.freebsd.org/D29262
- bhyve - Capsicum integration - https://reviews.freebsd.org/D30471
- Live migration for bhyve - https://reviews.freebsd.org/D30954

Beside the opened reviews, we are working on various projects (are
described in the wiki as well) that are still not ready for a review
on Phabricator yet:
- checkpoint option for bhyve either using ZFS or libvdsk - we have a
PoC for ZFS [2][3] and are working for adding QCOW2 checkpoint
functionality to libvdsk and then link it to the bhyve checkpoint
functionality.
- USB-passthrough - we managed to pass-through a keyboard to a bhyve
Linux VM, we are working on reattaching the USB device to the host
when exiting the VM and then we plan to check the functionality with
an USB stick (storage transfer).
- AMD CPU support for the save restore - we are running the final
tests before opening a ticket on Phabricator.
- use FreeBSD as a compute node in OpenStack

If you have any questions, please let us know.

Quite frustrating actually so I'd appreciate some help if mini-projects are acceptable.
