Hello,

is Proxmox VE able to "disable / unpower / send to deep sleep" a PCIe card if the VM to which the card is passed through is powered off?

Thanks a lot in advance,

Thomas

No, you usually have to run a small VM that has a driver for the device that can put it in low(est) power mode. GPUs, for example, will otherwise be in VGA boot mode (waiting for the BIOS to activate them). I have seen threads about this before (that you might search for on this forum) that might contain more suggestions (like using hookscripts and/or loading a driver on the Proxmox host).
