I'm recently started hitting this:
virtlogd[7095]: Client hit max requests limit 1. This may result in keep-alive timeouts. Consider tuning the max_client_requests server parameter
virtqemud[7034]: internal error: connection closed due to keepalive timeout
This cause the VM to froze for some time and in some cases I needed to force quit the Boxes as they are not responding.
This is happening on Fedora 39 Silverblue.
