Obtaining Debugging Logs
~~~~~~~~~~~~~~~~~~~~~~~~
In case `pct start` is unable to start a specific container, it might be
helpful to collect debugging output by running `lxc-start` (replace `ID` with
the container's ID):
lxc-start -n ID -F -l DEBUG -o /tmp/lxc-ID.log
This command will attempt to start the container in foreground mode, to stop the container run `pct shutdown ID` or `pct stop ID` in a second terminal.
The collected debug log is written to `/tmp/lxc-ID.log`.
NOTE: If you have changed the container's configuration since the last start
attempt with `pct start`, you need to run `pct start` at least once to also
update the configuration used by `lxc-start`.
