I'm going to try what you said. First of all, I would know how to restore my previous settings. You said to do chmod a+rw /dev/sda*. Ok, now I've changed permissions. What can I do to return to my previous situation?

No I can't. Either I do 'linux ubd0=rootfs.debian.etch ubd1=swapfs.debian ubd2=/dev/hdc ubd3=/dev/sda eth0=tuntap,,,192.168.1.101 mem=512M noprocmm' or 'linux ubd0=rootfs.debian.etch ubd1=swapfs.debian ubd2=/dev/hdc ubd3=/dev/sda1 eth0=tuntap,,,192.168.1.101 mem=512M noprocmm' . Also, if I run UML with the last command, (with ubd3=/dev/sda1, obviously is not correct) i get "Kernel panic - not syncing: Segfault with no mm" ... There was only one time I booted UML successifully with that option. Anyway.. That's all..
