Your kernel config shows you that you have 9P support compiled as a loadable kernel modules. Now you need to load these modules into your running kernel: modprobe 9pnet modprobe 9pnet_virtio You can verify this with . lsmod | grep 9p Try now your mount commands, etc. If you want to have these modules loaded after reboot add them to /etc/modules.conf. The progress of their work can already be seen in Windows 10 Build 18836 that shows WSL/Linux File System in File Explorer. Access Linux Files in Command Line. In addition to File Explorer, you can use the classic Command Prompt, and PowerShell tools to access your Linux files. As of RHEL7, the recommended general-purpose file service is NFS; if it is not enough for your purpose, raising a ticket through your regular Red Hat support channels will make your needs known to the support, product management and development teams. I don't know the reason why CONFIG_9P_FS was enabled in RHEL6...

In case of media with limited number of write cycles (e.g. some flash drives) "sync" may cause life-cycle shortening. user. Allow an ordinary user to mount the filesystem. Just to add a bit, both the Linux client implementation and several servers are under active development, so I'd say that's a pretty clear sign that folks still have use for it. One of the areas its seen heavy use more recently is the virtio-9P (aka virtfs) which is part of qemu/kvm and can be used for direct guest to host file access.

9P (or the Plan 9 Filesystem Protocol) is a network protocol developed for the Plan 9 from Bell Labs distributed operating system as the means of connecting the components of a Plan 9 system. 9P was revised for the 4th edition of Plan 9 under the name 9P2000 that contained various fundamental improvements.

It is a replacement for 9pfuse from plan9port. Unlike 9pfuse, it works equally well on Linux, OpenBSD, FreeBSD, and any other OS with a FUSE implementation. .

The 9p filesystem. So the new network filesystem that may finally obsolete NFS (the cobol of filesystems) is the Plan 9 protocol. Plan 9 from Bell Labs is the operating system that the inventors of Unix (Ken Thompson and friends at Bell Labs) went on to create in the 90's.

Is there a native way to share filesystem space between CentOS host and guest without using 9p? If 9p is required, what distros support this out of the box? I have considered other methods of sharing filesystem such as NFS, but I would prefer a local solution rather than going over the network if possible. The 9p filesystem.

Contrary to most other operating systems, Plan 9's design is heavily distributed: while in other OS worlds, there are many (and often large) libraries and frameworks for common things, Plan 9 encapsulates them into fileservers.
