I am delighted to announce the release of virtio-fs v0.3, a shared file
system that lets virtual machines access a directory tree on the host.
This release is based on QEMU 4.1.0 and Linux 5.3-rc3.
Good news! As virtio-fs is maturing and stabilizing, what's the plan for
upstreaming both qemu and kernel part of it?
Cheers,
Tao

This is a development release aimed at early adopters of virtio-fs. Work is
being done to upstream the code into Linux and QEMU. We expect to stop
publishing virtio-fs releases once the code has been merged by these upstream
projects.
Where to get it:
https://gitlab.com/virtio-fs/linux/-/tags/virtio-fs-v0.3
https://gitlab.com/virtio-fs/qemu/-/tags/virtio-fs-v0.3
Changes:
* Please note that the mount syntax has changed to:
# mount -t virtio_fs myfs /mnt -o ...
The old syntax was "mount -t virtio_fs none /mnt -o tag=myfs,...".
* virtiofsd --fd=FDNUM takes a listen socket file descriptor number. File
descriptor passing is an alternative way to manage the vhost-user UNIX
domain socket. The parent process no longer needs to wait for virtiofsd to
create the listen socket before spawning the VM.
* virtiofsd --syslog logs to syslog(2) instead of stderr. Useful for unifying
logging and when the virtiofsd process is not being supervised.
* virtiofsd --thread-pool-size=NUM sets the maximum number of worker threads
for FUSE request processing. This can be used to control the host queue
depth. The default is 64.
* Performance improvements and bug fixes.
Note for Kata Containers: the new kernel is not compatible with existing
Kata Containers releases due to the mount syntax change. To try it out,
please apply the following kata-runtime patch:
https://gitlab.com/virtio-fs/runtime/commit/a2e44de817e438c02a495cf258039774527e3178
Kata Containers patches for virtio-fs v0.3 are under development and will be
submitted to Kata soon.
