                SSH between Mac OS X host and Virtual Box guest
              
          
    On Mac OS (host):

Shutdown your VM and do:
VirtualBox > Settings > Network > Add (you will get vboxnet0)
On a terminal ifconfig will show you new interface vboxnet0
VM's Settings > System > check "Enable I/O APIC."
VM's Settings > Network > Adapter 2 > host-only vboxnet0

sudo defaults write /Library/Preferences/com.apple.windowserver DisplayResolutionEnabled -bool YES;
sudo defaults delete /Library/Preferences/com.apple.windowserver DisplayResolutionDisabled;

// by the way, you need to logout and log back in for this to take effect.  Or at least that's what
// Quartz Debug says.  Who knows, maybe it's lying?

// P.S. Go to [Apple menu --> System Preferences --> Displays --> Display --> Scaled] after logging
// back in, and you'll see a bunch of "HiDPI" resolutions in the list to choose from.
