You could add a min_ram field to QEMUMachine along the lines of the max_ram patch I submitted earlier this week: http://patchwork.ozlabs.org/patch/87807/ and then have vl.c clamp the default RAM size to be at least the minimum. (I actually thought about implementing that in the patch but I didn't have a use case for it at the time...) -- PMM
