[downstream clone - 4.2.6] [PPC64LE] enable memory hotplug support
Last modified: 2018-09-11 10:44:52 EDT
+++ 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 +++ (Originally by michal.skrivanek)
AFAICT only bug 1282833 is ppc64 specific, the other two appear to be x86 as well. Is that correct? (Originally by David Gibson)
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 (Originally by michal.skrivanek)
(In reply to David Gibson from comment #1) > AFAICT only bug 1282833 is ppc64 specific, the other two appear to be x86 as > well. Is that correct? 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 (Originally by michal.skrivanek)
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 (Originally by michal.skrivanek)
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)
platform side is not ready yet, would need to push this out to 4.1 (Originally by michal.skrivanek)
likely need to wait for 7.5 (Originally by michal.skrivanek)
should work now with 7.5 (Originally by michal.skrivanek)
