====== VirtualBox Stuff ======

Dumping this here... from my blog...

VirtualBox EFI Screen Resolution <file text vbox_screenres.txt>
The window of a VirtualBox VM with EFI boot simply cannot fit my laptop screen - and I hate running a VM with scrollbars. So, after looking around for while, I found the solution. Understandably, it requires running command line.

    VBoxManage setextradata LiveBox VBoxInternal2/EfiGraphicsResolution 800x600

I want the window for my VM (LiveBox) to be at most 800x600. We can check that value by running,

     VBoxManage getextradata LiveBox VBoxInternal2/EfiGraphicsResolution

While we are at it, to view the current firmware used by a VM,

    VBoxManage showvminfo LiveBox | grep Firmware

And, finally, to actually select a firmware (options: bios / efi),

    VBoxManage modifyvm LiveBox --firmware efi

That's about that.

VirtualBox EFI Shell<file text vbox_efi_shell.txt>
I am using VirtualBox quite a bit (I occasionally go qemu from time to time), especially to test my live Linux builds. I now mostly setup my virtual machines to have the EFI boot enabled. However, whenever I do an installation, the machine will most of the time stop at a UEFI shell prompt.

To boot the previously installed system, you need to identity your EFI partition (e.g. fs0) from the listed devices and look for the path to the bootloader (e.g. grubx64.efi). You can type (these are case insensitive),

    FS0:
    \EFI\ubuntu\grubx64.efi

It should now boot. But, you will still get that prompt on the next boot. To make it permanent,

    FS0:
    edit startup.nsh

That will start a text editor. Write exactly what we typed before to boot. Press <Ctrl+s> and <Enter> to save, and <Ctrl+q> to quit. Now, your bootloader should execute when the system starts.
