[Qemu-devel] [RFC PATCH] qemu-log: Open file for logging when specified |
Date: |

qemu-log defaults to stderr when there is no '-D' option mentioned on command
line. When '-D' option is specified, we also need to specify '-d' option for it
to use the specified logfile. When using monitor to enable logging this is
troublesome since there will be no '-d' option because of which monitor dumps
the logs to stderr.
Fix this by opening the log file when '-D' is specified on the command line.
Also fix an ancient comment which does not hold true since changing location and
log level has now been streamlined.
