AES-NI Instructions Not Passed to Guest

Description
I'm running a Debian 9 x64 host on AMD AM1 (5350 CPU) hardware. AES-NI instructions are not being passed to a pfsense guest, all the right BIOS options are turned on. I installed VirtualBox 5.1 from your repo.
I tried hosting the same version of pfsense on a Windows 10 PC with an i7 CPU and the AES-NI instructions do get passed (so it's not an issue with pfsense receiving the instructions).
Why the issue in Linux?
There are some 2-3 year old bugs on here that flag this bug but they are marked as fixed.

Log file attached, thanks. SVM is enabled in the BIOS and AES is listed in the host's /proc/cpuinfo

You are correct that AES instructions are still disabled. Work is in progress to fix this problem (no ETA though, sorry).

Actually the reason why these instructions are not enabled for your guest have a different reason: For some reason you disabled 'nested paging' for your guest. Enable that feature in the VM settings and these instructions are passed through your guest.
Please attach a VBox.log file of such a VM session when AES-NI instructions are not passed to the guest.
