I wrote earlier about my life-long affair with NFS. 25 years of my life have gone into rpc portmappers and nis etc. But, so many letters in NFS, is there a better way? Enter 9p.
This post has a pretty good description. But, in a nutshell, 9p will use virtio transport, so no IP, no NFS, no lockers. Just seamless directory in both spots.
mount -t 9p -o trans=virtio,version=9p2000.L /hostpath /guestpath
ps, I know a lot of you are secret bunny lovers (not in that way!), so I included a picture of Glenda,the Plan-9 bunny.
