yes or libxl_primary_console_exec() so if the -e arg is specified you'll
need it to go into libxl_console_exec() as well.

it will be passed to the xenconsole program from step 3 above.

You will have to add a parameter and default it to NULL and that will
cause the underlying call to execl() to not specify that option.

Not sure I understand.

tools/console/client/main.c you'll find ESCAPE_CHARACTER hard coded.
You'll have to add an option here that execl() above in step 3 will
specify to pass the argument and utilize it.

Hopefully my comments above made sense. I'll be in the office the rest
of the week so I should be able to help if you run into any other
