from the search, I see discussion from 2018 about a related hard freeze, is it still an issue 2 ears later?

so I need to demote the rest of testing is priority to below 500?

you are correct, free an main has the same priority as stable.
I need to demote them correct?

I have no choice, as reported in this post: https://lists.debian.org/debian-user/2020/07/msg00114.html
I'm having issues passing an wireless usb adapter to a vm.
tested the adapter on my main machine working with latest libvirt, qemu and kernel in the same logic (vm usb passing) and it works great.
so I've upgraded the kernel to 5.6 (on the main machine I have 5.7 but I doubt it is the cause), now I want to upgrade libvirt and kvm to the testing one to see if the issue is solved.
