Re: Bhyve CD-ROM

*This is the truth : *

*YanVugenfirer <https://github.com/YanVugenfirer> *

-s 9,virtio-9p,sharename=/mnt \

This is not the right device. The right device is virtio-fs. Not knowing
bvyve, this probably should be -s 9,virtio-fs,<virtio-fs specific
parameters>

unfortunately If I do :

-s 9,virtio-fs,sharename=/mnt \

it does not work : so I suppose that bhyve does not support virtio-fs. Can
someone confirm this ?
