Comment 11 for bug 1720887

Submitted upstream to increase the limit in regard to what we found (4 per guest).
Also we had similar discussions for disks on s390x, so doing those in one shot.

Further on I'm waiting for some data/insight on why the original system has a lower limit than what the service configures.
