Did you make a directory inside your VM called /home/daylend/UbuntuServer and then reboot or mount -a to reload fstab?
I did the following:
Then I created the Directory "/unraid" not that the exact path matters could have used "/mnt/unraid" for instance and used that below instead of /unraid.
Then I added the following to fstab and rebooted:
unraid /unraid 9p trans=virtio,version=9p2000.L,_netdev,rw 0 0
And I got my user shares from my unRAID server listed when I "ls /unraid"
Hope this helps.
