[Qemu-devel] [PATCH v6 1/3] Check if GlobalProperty exists before registering |
Date: |
Wed, 18 Jul 2012 15:02:35 -0300 |
If a GlobalProperty has already been registered, it won't have its value
overwritten. This is done to enforce that the properties specified in the
command
line will "win" over the ones specified by the machine properties, if set with
the parameter "-M".
