Hi! As far as I can see there is no kvm in the base repository but the older version 36 in CentOS-Extras. Version 83 that belongs to 5.4 is only found on the install DVD and CD-Set. So it's different when installing kvm later with yum which results in kvm-36 than choosing 'Virtualization' on DVD install that installs kvm-83. It's also a difference between installing from network

The OOM notifier is getting deprecated to use for the reasons mentioned here by Michal Hocko: https://lkml.org/lkml/2018/7/12/314 This patch replaces the virtio-balloon oom notifier with a shrinker to release balloon pages on memory pressure. In addition, the bug in the replaced virtballoon_oom_notify that only VIRTIO_BALLOON_ARRAY_PFNS_MAX (i.e 256) balloon pages can be freed though the user

It would be interesting, especially because the users who are interested are people creating VMs allocated with lots of extra memory (for the worst case) but most of the time migrating when it's fairly idle.
