You need to tell your guest kernel to use it, otherwise it is just another disk available for use. mkswap /dev/ubdb swapon /dev/ubdb

Problem is that the code does what you tell it (not) to do and not what you expect it to do. ;) Antoine > but can anyone please tell me why I don't see swap space in > UML?
