On confidential guests when the KVM virtual machine file descriptor changes as
a part of the reset process, event file descriptors needs to be reassociated
with the new KVM VM file descriptor. This is achieved with the help of a
callback handler that gets called when KVM VM file descriptor changes during
the confidential guest reset process.

Have you actually tested confidential guests with VMBus or is this a change
"for completeness sake" that can't be exercised in the current state of things?
No I have not tested the changes with VMBus. It’s more for completeness sake as
you have correctly put it. If you suggest, I can drop the change.
I have mixed feelings here: on the one hand this support could be useful in
the future, on the other hand we probably don't want to add dead and
untestable code to QEMU.
Let's see what other maintainers think about adding such code in order to
be consistent across different subsystems.
Thanks,
Maciej
