How do I set default PID and GID for files created from a VM?

[gstacks13]

I've got an Ubuntu Server VM that I mount some shares to via virtiofs.  I have corresponding fstab entries for these that look like this:

 

media   /mnt/media   virtiofs rw,relatime 0 0

 

However, when I create or edit files in these shares from the VM, it gives me an owner of my username, and a GID 1000.  Ideally I'd want the group to be "users" so my docker containers could perform operations on these files as well, but I cannot for the life of me figure out how to do this. Is there a way?

Does anyone have a solution for this? I haven't had any luck getting either a 9P or VirtioFS mount to have the correct owner for files created in the VM.
