Mate Problem Description:
I currently have ubuntu server (24.04) running inside a qemu vm. I have set up a shared
folder between said server and my host using virtiofs. The Jellyfin server is setup in my vm and I access it via firefox on my host using firefox 192.168.1.3:8096. Everything has been working fine for sometime. (I actually watch the Jellyfin media on my TV rather than my host pc).
Now when I access the Jellyfin server via firefox on my host I cannot lauch/run any media files (mp4). Looking at the Jellyfin log it looks like I have a permission problem:
[2026-04-10 07:14:26.856 +00:00] [ERR] Permission error for Directory watcher: "/mnt/hostshare"
System.UnauthorizedAccessException: Access to the path '/mnt/hostshare' is denied.
---> System.IO.IOException: Permission denied
Why this has started is a mystery. /mnt/hostshare is the mount within my ubuntu server vm/Jellyfin client. Also attached is the setting of the virtiofs for my vm.

If a post answers a question, please check the “solved” box. It means that the poster is recognised for their help and it makes it easier for others to find the solution.
Apologies - I thought I had marked it as solved. I ticked the arrow, as shown below, and from memory it went from grey to bold. I will do it again. I read your link to me but it did not, to me, show me how exactly to mark a post/comment as solved. For me this site is not as intuitive to use as some sites - I can only apologise and hope my apology is accepted.
