" .Virtualbox " is a hidden directory placed in
Reusing it is possible, using tar to pack it, and then
unpack to other user's /home/other-user/
It goes like this
'tar -cf myVirtualbox.tar .Virtualbox/'
'sudo mkdir /usr/local/tmp'
'sudo cp myVirtualbox.tar /usr/local/tmp'
Then log out, next login as other user and
1) 'cp /usr/local/tmp/myVirtualbox.tar .'
( the dot means the current directory )
2) You may want to remove the currently existing
.Virtualbox, in order not to confuse things,
before doing 3).
3) 'tar xvf myVirtualbox.tar' : Then you have it all
at the "other-user".
( Copying or linking the original .Virtualbox
somewhere else will not work )
