200 MiB is a bit to specific to have no reason behind it, did you check
up on that? Maybe something can be found in PVE's git/patch history.
I have some faint remembrance that we had to increase the area we zero
out for ceph OSDs and/or for the installer.

Or do you have any references for why this should still be sufficient?
