[SOLVED] LXC: hardware drivers necessary on PVE host?

[TheHellSite]

Just a quick question (mainly) for the PVE developers.

When passing through a device to an LXC is it necessary to ALSO install the drivers for that device on the PVE host?
Or is it enough to install them in the LXC? (so the PVE host OS remains untouched)

I passed through the iGPU of my AMD APU to an LXC for hardware transcoding and it is basically working. What makes me wonder is that many other tutorials suggest to also install the drivers on the PVE host. Which I think is not necessary at all.

hi,

Which I think is not necessary at all.

it's not necessary at least i can't think of any reason ^^

What makes me wonder is that many other tutorials suggest to also install the drivers on the PVE host.

any specific example?

Thanks for confirming. This is what I was thinking too.

any specific example?

They don't say to also install it on the host, but to only install them on the host. Which is also kind of wrong if using LXCs, IMO.

they do say to install it on both:

1. Install the required drivers on the Proxmox host
...
4. Install the required drivers in your container.

one reason could be for nvidia, see the example config they have, which mounts devices from /dev/nvidia0 and so on. those may not be present without the driver -- though i'm not sure.

I passed through the iGPU of my AMD

but for that it's likely not necessary ^^
