Description

Steps to reproduce the issue:

System: Fedora 31, completely up-to-date (date: 2020.03.16, kernel: 5.5.8-200.fc31.x86_64)

podman run hello-world

Describe the results you received:

ERRO[0000] unable to write pod event: "open : no such file or directory" 
ERRO[0000] unable to write pod event: "open : no such file or directory" 
ERRO[0000] unable to write pod event: "open : no such file or directory" 

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

ERRO[0000] unable to write pod event: "open : no such file or directory" 
ERRO[0000] unable to write pod event: "open : no such file or directory" 

Describe the results you expected:

The same, withouth the ERRO-messages.

Additional information you deem important (e.g. issue happens only occasionally):

If I run sudo podman run hello-world, I don’t get these messages.
