Explore an innovative approach to accelerate file access in virtual machines and containers through an SPDK vhost FUSE Target. Delve into the recently proposed Virtio-fs solution for file system sharing in lightweight VMs and containers where shared volumes are essential. Learn about the SPDK (Storage Performance Development Kit) userspace vhost-user-fs solution that works in conjunction with QEMU/Kata Container to enhance virtio-fs performance. Discover how this solution leverages techniques such as virtio-fs and blobfs (SPDK file system) to achieve significant performance gains. Understand the implementation details, including how blobfs can be constructed on an abstract block device layer in SPDK, enabling access to local or remote storage services via iSCSI/NVMe/NVMeoF protocols in userspace. Gain insights into building a fast, consistent, and secure method for sharing directory trees from host to guests using this innovative approach.
