Re: [PATCH] bhyve: implement virtio-9p support

Recently virtio-9p support was added to bhyve. On the host side it looks this way: bhyve .... -s 25:0,virtio-9p,sharename=/path/to/shared/dir It could also have ",ro" suffix to make share read-only. In the Linux guest, this share is mounted with: mount -t 9p sharename /mnt/sharename In the guest user will see the same permissions and ownership information for this directory as on the host. No uid/gid remapping is supported, so those could resolve to wrong user or group names. The same applies to the other side: chowning/chmodding in the guest will set specified ownership and permissions on the host. In libvirt domain XML it's modeled using the 'filesystem' element: <filesystem type='mount'> <source dir='/path/to/shared/dir'/> <target dir='sharename'/> </filesystem> Optional 'readonly' sub-element enables read-only mode.
