[SOLVED] AMD (3dnow) Processor emulation? Intel CPU on host.

I have an old appliance (PBX system) that runs on an embedded system, AMD something


My Proxmox host is Intel(R) Xeon(R) CPU L5640.
I have imaged the boot disk and tried to boot the embedded system, and the embedded kernel complains there is no 3d now support on the cpu. I have tried to switch to various CPU profiles (Athlon/Phenom etc) but Proxmox complains the host doesn't support those features.

Is there any way to emulate a few processor features such as 3dnow, I'm not worried about speed of the emulation at the moment, just getting it booting, if I can figure it out I will recompile the kernel for it.

I would like to completely virtualize this box but I need to poke around at the internals in a vm for a bit.

I have seen a few patches here and there to emulate 3dnow etc but I have no idea how to enable this on Proxmox or if they are included or not. Thank you.
Nevermind, figured it out!

Untick KVM Hardware virtualization and then the processor itself is emulated as well! :)
The image booted mostly.
