my host is slackware.
the virtual machine is windows xp.
I am going to add the folder in my slackware into the windows using samba in the slackware.
This is what I do.
Activate the shared folder using samba.
add the sharing line
restart the samba
Run the windows through Virtualbox
Go to My computer, type the host ip for browsing the share folder in the address bar box
Now we have a share folder from host to virtualbox machine.
