I must note, this section is in C code and not Python, as it is part of
xc_dumpcore() in libxc. I understand that it is better to log the error
as soon as possible, but logging takes place at the Python layer above.

Yes, I do think that is is necessary to mention a pause. There are times
when the user will send an Interrupt with say, CTRL+C at the middle of
dumping. Of course, xm dump will terminate, but the domU will continue
to be paused and it will have to be unpaused manually. Of course, if you
read the inner workings I wrote you would understand, but I think it
will save a lot of people time wondering why their domain froze.
