Unless you are running the VM GUI in debug mode ( pvcsvmux - d ), the stdout channel is closed because we are launching the GUI in background mode and want to reduce its chattiness. Unfortunately there are a number of critical error messages that are sent via stdout, all of which effectively fail to get displayed. Example:
