This wouldn't matter, since UML is using hostfs (which does not support XATTR at all, to my knowledge) and not ext2/ext3. > But after I recompiled the kernel of > UML and run it, I was given the same message mentioned above. > > What should do next? Could anybody give me some advices?
There are few reasons usually for using hostfs, normally using a dedicated root_fs is a better solution. And using hostfs on your / can cause trouble to both your host and your guest (well, if you boot with init=/bin/sh then there are less problems). -- Inform me of my mistakes, so I can add them to my list!
