Mount host dir to guest vm #8

Open johndo100 opened 2 months ago

I want to know how to mount host directory to guest vm.

Please help.

One way is to use network file systems such as NFS or SAMBA. These protocols may work for you if your VMs have network connectivity to the host OS. If you intend to use a virtio-9p device, the bmd doesn't support it now. I'm planning to add the configurations for virtio-9p. The guest FreeBSD is now able to use it by the following commit. It looks so fun.

Yes. Virtio-9p is exactly what I use to mount host dir when I'm on byhve-vm. Jail manager apps usually use something call nullfs but I'm not sure. Sorry my knowledge about it is little.

I added 'sharefs' keyword to the VM configuration. It has "[sharename] = [pathname]" value which is passed to the virtio-9p device.

I'm feeling sharing a file system is not a block device. Of course, virtio-9p is one of PCI device of the VM, but it's an implementation matter. For VM users, it looks easy to understand that 'disk' is used for block devices, and 'sharefs' is used for file systems.
