My concern here is that these files will pile up in the caches of the
various users -- especially the newly added qmp-schema cache is
(generated on my Fedora 26) a 90+ KB output. Every time qemu changes
there will at least 125/130+ KB used (10+ KB for devices, 25+ KB for
help, 90+ KB for qmp-schema), and those are never cleaned up
automatically.
It's a concern, but they're not very big relative to the size of the
appliance (236M here). Also they are eventually cleaned up because
they are located in /var/tmp, although that could be a very long time --
30 days on Fedora.
