Hi all, We have this field in the Vdsm API: - description: The amount of memory guaranteed to the VM in MB name: memGuaranteedSize type: uint Available in VmDefinition, VMFullInfo, VmParameters Vdsm dutifully records and reports this value - but doesn't use it. It is used exactly once for balloon stata: stats['balloonInfo'].update({ 'balloon_max': str(max_mem), 'balloon_min': str( int(vm.conf.get('memGuaranteedSize', '0')) * 1024), 'balloon_cur': str(balloon_cur), 'balloon_target': str(balloon_target) }) Now, a quick git grep in both MOM and Engine reveals no obvious usages. Am I missing something? Can we drop this for 4.2, and deprecate it in next(4.1) ? Thanks, -- Francesco Romani Senior SW Eng., Virtualization R&D Red Hat IRC: fromani github: @fromanirh
