[PATCH] qemu: warn on pausing of guest due to watchdog or io error

Posted by Michal Privoznik 1 month, 1 week ago

From: Lennart Fricke <lennart.fricke@drehpunkt.com>

Change the log level for pauses of guests due to watchdog timeouts
or io errors from debug to warn to enhance the visibility of such
events.
