Don't use "root=" at all. UML has a safe default. Also, IIRC, there were some strange problems, for which it uses root=98:0. > I checked in my guest root file system for > /dev/ubd/0. It is there, There is a device node at that point? Who prepared such a strange root_fs? Normally, that path is created by DevFS, which creates dynamically such a device node. > and also my guest root file > system has an entry for /dev/ubd/0 in /etc/fstab: > /dev/ubd/0 / ext2 defaults 1 1 The kernel hasn't still accessed the root fs, so what's in it doesn't matter at this point. It will matter later, though. The normal setup is to have device nodes in /dev/ubd[0-7], and the minors increasing by 16, and /etc/fstab referring to them. Also, make sure /etc/inittab uses names as tty1 - tty7, rather than vc/1 and such, in the *getty calls (it depends on DevFS too). However, you must conform to the device names in that root_fs - which are just strange. So be careful. -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
