Description RHV bug bot 2018-09-03 15:20:38 UTC
+++ This bug is a downstream clone. The original bug is: +++
+++   bug 1284775 +++
======================================================================

Temporarily disable hotplug memory support until issues (e.g. bug 1282833, bug 1273491, bug 1272742) are sorted out, then enable it:)

+++ This bug was initially created as a clone of Bug #1282833 +++

Comment 1 RHV bug bot 2018-09-03 15:20:55 UTC
AFAICT only bug 1282833 is ppc64 specific, the other two appear to be x86 as well.  Is that correct?

Comment 3 RHV bug bot 2018-09-03 15:21:06 UTC
so now we have the initial state of hotplug RAM not being enabled on POWER (patch 49072 in the closest to-be-published release).

From now on the bug tracks the required changes (or platform deliverables) to be able to enable it again and match x86 parity as soon as it is deemed stable

right. however there are more situations, now QE run into bug 1285474, which I believe is the same thing about qemu memory hash tables being too large, just this time exposed on migration flow

Comment 5 RHV bug bot 2018-09-03 15:21:28 UTC
we tested that on current 7.2, still problematic (see related bugs), so we are going to keep hotplug disabled for now until the root issue is resolved

Comment 6 RHV bug bot 2018-09-03 15:21:38 UTC
moving to 4.0 as the bugs this one depends on are heavily in progress and won't be ready before RHEL 7.3

(Originally by michal.skrivanek)

Comment 8 RHV bug bot 2018-09-03 15:21:58 UTC
platform side is not ready yet, would need to push this out to 4.1

(Originally by michal.skrivanek)

Comment 10 RHV bug bot 2018-09-03 15:22:19 UTC
likely need to wait for 7.5

(Originally by michal.skrivanek)

Comment 11 RHV bug bot 2018-09-03 15:22:29 UTC
should work now with 7.5
