Re: [Xen-devel] [PATCH] tools: xl: add option to run in foreground but still monitor for reboot etc

[Olaf Hering <olaf@xxxxxxxxx>]

Ian,


the xl migrate command gets a new option -F with this change.
Is it intentional? The "monitor" variable is not used in this part of
the patch.
It got applied in changeset 23350:f531ed84b066
