PVE blank screen (iLO) after boot with GPU hosts

icepicknz · May 9, 2023

Hey guys,

I have 3 pve hosts in a cluster, two of them have GPU's for passthrough to VM's which is all working great.
When accessing the two hosts via iLO that have GPU's I get a blank screen, so in an emergency situation I'd be screwed.

I'm not sure if this is Proxmox OS related or iLO / Bios related, to use the internal graphics rather than GPU (I'm only assuming this is the issue).
Assuming, because the host with no GPU allows me to access shell via iLO.

Many thanks
Barry

you need to change the "video options" in the bios.

some made a tuturiol for the bios cli (should also be possible during the boot with a monitor):

Thanks for that; my experience was a little different, I tried the following, but once it got to PVE boot, I still get "No Video".
It appears I don't have an option "Embedded video primary"

After hitting ESC+9, I was presented with a text version of the bios configuration.
Going into RBSU, I found the following configuration and made changes
