- shared directory name - Arbitrary directory name that you want to share with Guest. I recommend using the same in Guest and Host to avoid confustion.
- virtual machine id - An ID of Virtual Machine that will have access to shared directory. The ID is visible in proxmox and will usually be 3 digit: 100, 101.. .
- mount tag - Unique tag that identifies which shared directory needs to be the same in both Host and Guest configuration.
$ zfs create -o mountpoint=/9pshare -o acltype=posixacl -o xattr=sa -o aclinherit=passthrough rpool/9pshare
$ mkdir /9pshare/<shared directory name>
$ nano /etc/pve/qemu-server/<virtual machine id>.confAdd a line that says:
args: -virtfs local,path=/9pshare/<shared directory name>,mount_tag=<mount tag>,security_model=mapped-xattr,id=fs0Save the file and start VM.
Make sure the following kernel modules are loaded: 9p, 9pnet, 9pnet_virtio.
Then edit the fstab file:
$ mkdir /<shared directory name>
$ nano /etc/fstabAdd the following line:
<mount tag> /<shared directory name> 9p trans=virtio,version=9p2000.L,nobootwait,rw,msize=524288,user_xattr,posixacl,_netdev 0 0Save fstab and check it for errors:
$ mount -aThat's all :)
