Took me quite a while to hunt down all the details. ESXi works great on these servers, they were built to run it, and have the pass through and sr-iov built in to the OS. Other OS’s require a little more effort. After some time I found this.

This article gives detailed instructions to exclude the pcie slot of your choice from the bios rmrr. Next issue is getting the HPE scripting toolkit to work on proxmox/debian: Use these HPE links:
https://downloads.linux.hpe.com/SDR/keys.html & https://downloads.linux.hpe.com/SDR/project/stk/
The actual code is:
curl https://downloads.linux.hpe.com/SDR/hpPublicKey2048.pub | apt-key add -
curl https://downloads.linux.hpe.com/SDR/hpPublicKey2048_key1.pub | apt-key add -
curl https://downloads.linux.hpe.com/SDR/hpePublicKey2048_key1.pub | apt-key add -
Then add a file called hpe.list to /etc/apt/sources.list.d
cat <<EOF >/etc/apt/sources.list.d/hpe.list
# HPE Scripting Tool Kit
deb http://downloads.linux.hpe.com/SDR/repo/stk buster/current non-free
EOF
then:
apt update
apt install hp-scripting-tools
This will install the scripts you need to run ‘conrep’ and modify the bios to exclude a pcie slot.
I have had issues passing hba cards using this method but have not tried using a gpu/video.
Cheers,
Mike
