I have VirtualBox 4.3.6 r91406 in a Mac OS X 10.9.1 Host.
I installed a Virtual Machine with MAC OS X 10.6 and I can increase the resolution of this Virtual Machine. In the Virtual Machine System Preferences I only have the resolution 1024 x 768 and no more
What should I do?

Re: How to increase resolution of a OS X VM in a OS X Host
From the User Manual, Section 3.12 Alternative firmware (EFI)
EFI provides two distinct video interfaces: GOP (Graphics Output Protocol) and UGA (Universal Graphics Adapter). Mac OS X uses GOP, while Linux tends to use UGA. VirtualBox provides a configuration option to control the framebuffer size for both interfaces.
To control GOP, use the following VBoxManage command:
VBoxManage setextradata "VM name" VBoxInternal2/EfiGopMode N
Where N can be one of 0,1,2,3,4,5 referring to the 640x480, 800x600, 1024x768, 1280x1024, 1440x900, 1920x1200 screen resolution respectively.
