B bakul 12 minutes ago #28 I use plain bhyve and have something like the following args to bhyve command line: -s 8,virtio-9p,src=/usr/src \ -s 9,virtio-9p,obj=/usr/obj \ Click to expand... Then in the freebsd guest /etc/fstab has entries like this: src /usr/src p9fs rw 0 0 obj /usr/obj p9fs rw 0 0 Click to expand... As for performance, see this -hackers post: https://lists.freebsd.org/archives/freebsd-hackers/2026-May/006363.html The uncached numbers for nfs are *worse* than I remembered! But warning: p9fs is used much less and tested much less so there may still be bugs. Sharing is still much worse so I usually just copy files to the VM's filesystem. I use nvme as virtual disk type, for example: " -s 5,nvme,disk.img \"
