what exactly do you mean with vGPU status?

there currently is no api to see which pci devices are in use of a vm
(though that could be done per node, not really for mediated devices though)

there is the /nodes/NODENAME/hardware/pci api call which shows what devices exist
and if they have mdev (mediated device) capability (e.g. NVIDIA GRID vGPU)

for those cards there also exists the api call

/nodes/NODENAME/hardware/pci/PCIID/mdev

which gives a list of mdev types and how many are available of them


does that help?

if you have more specific requirements (or i misunderstood you), please
open a bug/feature request on https://bugzilla.proxmox.com
