[libvirt] [ANNOUNCE] virtio-fs v0.2 host<->guest file system released

[Stefan Hajnoczi]

Dear QEMU, KVM, and libvirt communities,
virtio-fs is a shared file system that lets virtual machines access a
directory tree on the host.  Unlike existing approaches, it is designed
to offer local file system semantics and performance.  The guest can
take advantage of Linux DAX to access file contents directly from the
host page cache, eliminating the need to copy data into guest memory.

We hope virtio-fs will become widely available and easily accessible
through libvirt, Kata Containers, and popular management tools.

For more information, visit https://virtio-fs.gitlab.io/.
Mailing list: https://www.redhat.com/mailman/listinfo/virtio-fs
IRC: #virtio-fs on chat.freenode.net

The v0.2 release incorporates stabilization, performance, and sandboxing
improvements that now make virtio-fs suitable for testing and
performance evaluation.

Please do not rely on virtio-fs for production data yet.  Consider it
experimental.

Guides are available for:
 * Manually running QEMU with virtio-fs
