### Solution ### Solution
You will need to remove the hanging gv-proxy process bound to the port in question. For example, if the port mentioned in the error message is 127.0.0.1:7777, you can use the command `kill -9 $(lsof -i:7777)` in order to identify and remove the hanging process which prevents you from starting a new VM on that default port.

### 32) The sshd process fails to run inside of the container.
#### Symptom
The sshd process running inside the container fails with the error
"Error writing /proc/self/loginuid".
### Solution
If the `/proc/self/loginuid` file is already initialized then the
`CAP_AUDIT_CONTROL` capability is required to override it.
This happens when running Podman from a user session since the
`/proc/self/loginuid` file is already initialized. The solution is to
run Podman from a system service, either using the Podman service, and
then using podman -remote to start the container or simply by running
something like `systemd-run podman run ...`. In this case the
container will only need `CAP_AUDIT_WRITE`.
