Hi @Dinh_Hoang,
Your Core i5-8350U CPU looks like it should have the right feature support, but your /proc/cpuinfo output is missing AVX extensions.
Can you confirm:
- version of VirtualBox used
- host O/S
It looks like there are a few conditions for AVX support in VirtualBox:
- You should be using VirtualBox 5.03 or later
- You need to disable Hyper-V on a Windows host:
Normally Hyper-V blocks Virtualbox. Hyper-V is a type-1 hypervisor, which accesses the hardware first before any OS runs, and therefore interferes with other programs that need “virtualization technology”, like Virtualbox, which is a type-2 Hypervisor.
