[For me] notes Ubuntu (hay gặp)

VMWare:
/mnt/hfgs empty:
- manually re-install vmware tool: https://www.youtube.com/watch?v=cbekWwH6AEo
- restart
- terminal:  sudo vmware-config-tools.pl -d --clobber-kernel-modules=vmhgfs

VirtualBox:
VirtualBox -> settings -> ShareFolder: does not work
ref: http://askubuntu.com/questions/456400/why-cant-i-access-a-shared-folder-from-within-my-virtualbox-machine

install Guest Additions

1. Start your VM
2. Devices > Insert Guest Additions CD image

mount your share using:

mkdir ~/new
sudo mount -t vboxsf New ~/new

Where New is the name of your shared folder.

Now you can access the shared folder at ~/new.
