Qubes Manager: can't remove device assignment for nonexistent device

[kbrn]

Qubes OS version (e.g., R3.2):

R3.2

Affected TemplateVMs (e.g., fedora-23, if applicable):

N/A (dom0)

---

Expected behavior:

After disabling a device in my BIOS menu, I tried to start a VM to which that device had previously been assigned. That VM failed to start. I expected to be able to remove the design assignment with Qubes Manager's Settings dialog.

Actual behavior:

There was no way to remove the now-nonexistent device assignment with Qubes Manager. I had to close Qubes Manager and edit qubes.xml by hand.

Steps to reproduce the behavior:

Assign a device on the PCI bus to a VM. Shut down your machine. Remove or disable the PCI device. Reboot and try to start that VM. Try to remove the device assignment from the VM using Qubes Manager.

General notes:

None.

I'm curious whether qvm-prefs would have worked. Did you happen to try it?

qvm-pci also should work.
