SOLVED: Hardware Acceleration

If "azha" is the proxmox host itself, then you need to install a bunch of packages on proxmox.

Code:

apt install linux-headers-amd64 intel-gpu-tools intel-media-va-driver-non-free intel-microcode libdrm-intel1

I know that vanilla Debian doesn't configure apt to pull from the non-free repo. Not sure if Proxmox is the same. If it isn't installing the non-free intel media driver, add "non-free" to your apt config.
