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?We're working on that. A few days ago I sent the core qemu code to qemu-devel marked as experiemental; Vivek is planning on sending another kernel version out.
Cool. Looking forward to seeing them in upstream code base;) Cheers, Tao
DaveCheers, TaoFor more information about virtio-fs: https://virtio-fs.gitlab.io/ 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.
