Output of cat /proc/cpuinfo on the host machine using Cygwin - it has avx in avx2.

Following advice from existing threads, I ran VBoxManage setextradata "Ubuntu20" VBoxInternal/CPUM/IsaExts/AVX 1 and VBoxManage setextradata "Ubuntu20" VBoxInternal/CPUM/IsaExts/AVX2 1 on the host machine and restarted the guest machine - nothing changed (the guest machine's name is Ubuntu20).

On guest machine (Ubuntu 20.04 64bit using VirtualBox 6.1.16, same happens with 18.04), AVX and AVX2 are missing.

My host machine (Windows 10 64bit) has AVX and AVX2 (validated using Cygwin, see more details below).

Tensorflow 1.15 crashes on my virtual machine when imported by Python (error message is Illegal instruction (core dumped)), very probably thanks to AVX and AVX2 being disabled on it.
