I'm certainly up for mentoring new devices for vhost-device (rust-vmm
vhost-user backends). Since we've become a code owner we're trying to
clear the backlog (virto-vsock and virtio-block) but there are plenty of
others that could be done. Of particular interest to me are:

  - virtio-rpmb (we have a working C implementation I wrote)
  - virtio-snd (in flight virtio spec)
  - virtio-video (again we have a working C version against v3)

With my other hat on there are numerous TCG plugin projects that could
be done. Adding basic plugins is fairly straight forward but it would be
interesting to look at what is required to do a more involved plugin
like panda-re's taint analysis (following ptrs as they move through the
system). This will likely need some additional features exposed from the
plugin interface to achieve.

With that in mind there is also the idea of a central registry for
register values which is a prerequisite for expanding access to TCG
plugins but could also bring various quality of life improvements to
other areas. I've written that up on a page:
