Ok, now it's more clear as regards chmod. I didn't read as well as I did just before.
I'm actually trying to mount my pendrive, always without results. Maybe I'll give up soon. It seems something impossible. O_O My last attempt was to do chmod a+rw /dev/sda* on my host.. Infact, now these are /dev/sda* right access: # ls -l /dev/sda* brw-rw-rw- 1 root disk 8, 0 Nov 10 22:56 /dev/sda brw-rw-rw- 1 root disk 8, 1 Nov 10 22:56 /dev/sda1 But now, adding "ubdc1=/dev/sda1" (Jeff said to associate with ubdc1, as I did understand correctly) to kernel command line I can't get something positive. Attempting to mount my pen-drive on the guest system I'm giving the same result: ~# mount -t vfat /dev/ubdc1 /mnt/pendrive/ mount: /dev/ubdc1 is not a valid block device I don't know now, if it's really possible!!!!!
