Thx for crosschecking. Well it looks like docs are out of date, 256MB ram is definitely not enough. I already though about to extract it here and than copy it to the vm. However, uploading uncompressed kernel sources would take quite some time over my slow internet connection and i really wanted to avoid that. Anyway, either copy or buy a better vm. I guess i'll gonna make my own vm at home and copy the full system over... thx mmike
