I read in the manual that you should be able to set the video mode on Snow Leopard guest (EFI) with the command

Code: Select all

VBoxManage setextradata vmname VBoxInternal2/EfiGopMode N
Where N can be one of 0,1,2,3,4 referring to the 640x480, 800x600, 1024x768,
1280x1024, 1440x900 screen resolution respectively.
So I tried but get the error

Code: Select all

sudo VBoxManage setextradata SnowLep VBoxInternal2/EfiGopMode 3
Oracle VM VirtualBox Command Line Management Interface Version 3.2.4

ERROR: Could not find a registered machine named 'SnowLep'

Context: "FindMachine(Bstr(a->argv[0]), machine.asOutParam())" at line 583 of file VBoxManageMisc.cpp
If I do

Code: Select all

VBoxManage list vms
I get the name of the vm to be "SnowLep".

Also if I

Code: Select all

VBoxManage getextradata "SnowLep" enumerate

it finds the vm.

Could someone tell me what I am doing wrong with the statement that it won't change the resolution to 1280x1024?
Thank you.

What's wrong: sudo

Forget sudo.

When you use that you are trying to change root:s vm named SnowLep not your vm.
