We do not need the memory to be physcially hot added/removed. Instead we just want it to be logically offlined so that these memory blocks are no longer used by the OS which has offlined it and can be used by the second OS. Once it is done using the memory for a certain use case it can be returned back by onlining it. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
