VirtualBox help

[address@hidden]

Hey all,

In my GUB installation, my VirtualBox ran out of space and peetered out.
So, I closed my VirtualBox down, resized the hard drive, and tried to boot 
again.

However, it cannot restart (some message about GNOME power something something) 
and I think it's because the disk space is full.  It's not even recognizing my 
root password :-/
Does anyone know how to do delete files on a VBox from the outside so that I 
can free up space?  I know this question is more appropriate for a VirtualBox 
forum, but I figured that one of you may know...

Alternatively, if that doesn't work, does anyone know how to recover files from 
a virtual hard drive?

Cheers,
MS
