Try this script

tools/pve/gpu-passthrough.sh, run in the Proxmox VE shell:

bash -c "$(curl -fsSL https://raw.githubusercontent.com/cwmoriarty/DevScripts/gpu-passthrough/tools/pve/gpu-passthrough.sh)"

Against a core branch as well

Add COMMUNITY_SCRIPTS_CORE_URL=https://raw.githubusercontent.com/OWNER/core/BRANCH
to test an engine change at the same time. The two resolve independently.

Thanks.

Marking as >6 months, >600 stars so this can get reviewed.

Not sure how a PVE host toolt would or could get that much traction? I might be missing something in the process here.

That Count for normal Scripts, Not for pve tools
