Hello list

Did I forgot to ask you something, do not give him the solution to the
vm that has installed ubuntu 12.0 in my XCP, which would be the way to
edit the FSTAB file?

I already tried with live-CD, not let me mount it the disc, lagoon is
no way to mount virtual disk to edit the fstab file?

any comment is appreciated.

Ricardo
