VirtualBox tricks

cd "c:\Program Files\oracle\virtualbox"
VBoxManage setextradata "$vm_name" VBoxInternal/CPUM/IsaExts/AVX 0
VBoxManage setextradata "$vm_name" VBoxInternal/CPUM/IsaExts/AVX2 0

Change screen resiolution on iOS VB machine:

cd "c:\Program Files\oracle\virtualbox"

VBoxManage setextradata "$vm_name" VBoxInternal2/EfiGraphicsResolution 1920x1080

VirtualBox: Change Date and Time

If you want to change the time in a guest system in VirtualBox, by default, you can experience the following behavior: After changing the clock of an operating system that was launched from VirtualBox, it does not take long before the time is returning to its original state. It seems as if there is no chance to change the time.

<path to exe>\VBoxManage.exe setextradata <VirtualMachineName> "VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled" "1"
