I have a VM with a 9p share and nginx. It worked fine until I updated my VM to Debian 10. Since then, it fails to serve files from my 9p share. Nginx returns an empty response and 2020/09/11 09:57:49 [alert] 864#864: *449 pread() read only 4096 of 32768 from "/9p/test.png" while sending response to client Files under 4096 work. Anything over 4096 will fail. It always says 'read only 4096 of xxxx'. File cache isn't enabled. What could cause this?

One reason could be that 9p driver in guest kernel is incompatible with the 9p driver on host.

Try using same kernel on both guest and host.
