Hi tetrahedra,
The original error ("unable to reset PCI device...") still occurs when trying

Despite have the "no-strict-reset" set to True, you will continue to see the "Unable to reset

trying to attach a PCI device that does not support the FLR (Function Level Reset) [2].
The "no-strict-reset" enablement patch [1] allows you (libvirt) to assign a PCI
device to domU, even when the device does not support any reset method .
The error message is kept there for the informational purposes so this way a person may
become aware of that his PCI device may not be working as desired because it does not
support any reset method, despite of which it still gets assigned to domU when
"no-strict-reset" is set to True, thanks to the patch [1].
Hi Andrey,
All that may be true but it does not explain why the error message was
accompanying an *error condition* -- specifically that the VM refused to
start. If the error had simply been printed in the logs and the VM
started normally (with USB controllers) then it would not have been an
issue.

Despite have the "no-strict-reset" set to True, you will continue to see the
"Unable to reset PCI device: ... no FLR, PM reset or bus reset available"
"error" message each time you are trying to attach a PCI device that does not
support the FLR (Function Level Reset) [2].

device to domU, even when the device does not support any reset method .

person may become aware of that his PCI device may not be working as desired
because it does not support any reset method, despite of which it still gets
assigned to domU when "no-strict-reset" is set to True, thanks to the patch [1].
I think it'd be good to mention here the whole message from the
"no-strict-reset" patch:
> This allows to assign PCI device to some VM, even when the device does not
> support any reset method. This may be dangerous in some cases (especially
> when the device is later assigned to some other VM). But in some cases it

To check if your PCI device has a FLR function, run:
$ sudo lspci -vv -s 00:14.0
If you see output with "FLReset-" then your PCI device does not support FLR
function. If output has "FLReset+" then it does.
There are very few PCI devices which support FLR function.

[qubes-users] Firefox discontinues addon sideloading
Dear all, apparently Mozilla decided to discontinue that feature [1] without providing a lot of alternatives [2]. It was quite useful in the past to update addons inside Qubes OS template VMs by downloading them to another VM and pass them to the template VM without having to start firefox and perform a lot of clicking. That'll be gone. So does anyone have an alternative available apart from a dedicated template VM just for firefox? Update the addons on every disposable VM start? ^^ BR David [1] https://blog.mozilla.org/addons/2019/10/31/firefox-to-discontinue-sideloaded-extensions/ [2] https://discourse.mozilla.org/t/questions-on-sideloading-alternatives/49245 -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
