Device isn't assignable

  1. What could be the reasons device not used by any qube not to be shown as assignable when running sudo xl pci-assignable-list?

The problem is that if I want to assign such a device, I must hide it from dom0, to recreate grub and to reboot. If I want to get it back, the same process, reversed, which is cumbersome. How should I look for the reasons?

  1. What is the difference between
    xen-pciback.hide=(00:xx.x)
    and
    rd.qubes.hide_pci=00:xx.x

Pointing to documentation to read and learn is preferred.

Bump?

I’m not entirely sure and you will have to check yourself, but I think xen-pciback assign the pciback driver to the device, and rd.qubes.hide_pci assigns the module ?
