Xeon E5-2460 v2 SSE 4.2 and VM's

[paintballer4lfe]

I'm not sure if this is a configuration issue on the VM or possibly a SCALE issue but, I have a VM running ubuntu 22 on a fresh install of SCALE and it somehow does not support AVX/SSE 4.2. The processor itself can of course do AVX/SSE 4.2 but it seems SCALE does not. Is this a configuration thing on the VM that I need to tweak? I tried as many different CPU model configs as I could on the VM profile but it changed nothing.

Is there something I'm missing on this? The VM is needing to run a program that Go has an issue with since it is reporting it cannot do AVX.

I'm running an Ubuntu 20.04 VM on SCALE with passthrough CPU and a very similar processor. Not really sure what your issue is, but my VM reports AVX and SSE 4.2 as enabled:

Ah ha okay so I set it to host pass through and literally rebooted the VM 4+ times and it finally is showing avx on the VM. No clue why it took that long but it's working now oddly enough
