USB Controller Passthrough

[szafran]

Hi,

I've tried to PT my PCI-E USB controller to a vm, and each time I've tried to start the vm the whole PVE server stopped responding.

Do those mean I can't easily PT the controller?:

Or maybe there is something I can do to make it work ? (changing PCI-E port can't be done).

Best regards

you can try overriding the iommu groups
more information here : https://wiki.archlinux.org/index.ph...ing_the_IOMMU_groups_.28ACS_override_patch.29
(we have included that patch, so that should work; be aware of the consequences of this)

Thank you for the info. I'll think I'll stay away from this (at least for now).
