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

Hi Dominik,

any news about your patches "add cluster-wide hardware device mapping"
?

Do you think it'll be merged for proxmox 8 ?

I think it could help for this usecase.

i'm currently on a new version of this
first part was my recent series for the section config/api array support

i think i can send the new version for the backend this week

i don't know, but this also depends on the capacity of my colleagues to review ;)

You can refer them directly to me (d.csapak@proxmox.com) or our office mail (office@proxmox.com).
Maybe it helps if the request comes also from the customer side.

Normally i have my tests running with each update of the 5.15 kernel and i did not see
any special problems there. The only recent thing was that we had to change how we
clean up the mediated devices for their newer versions [0]

Note that i only test the latest supported GRID version though (Currently 15.2)

making it easy to digest and adding (good) tests will surely help to
accelerate this ;-P

But, you're naturally right, and tbh., while I'll try hard to get the access-control
and some other fundaments in, especially those where we can profit from the higher
freedom/flexibility of a major release, I cannot definitely say that the actual HW
mapping will make it for initial 8.0.

For initial major release I prefer having a bit less features but focus more on that
the existing features keep working and that there's a stable and well tested upgrade path.

Hi Dominik,

Do you have any expected timeline/version for this to be merged?

Thanks

the cluster wide device mapping was merged last year already and is included in pve 8.0 and
onwards. or do you mean something different?
