I may miss something but according to <a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://www.ovirt.org/Features/Hot_Plug_Memory"></a><a class="moz-txt-link-freetext" href="http://www.ovirt.org/Features/Hot_Plug_Memory">http://www.ovirt.org/Features/Hot_Plug_Memory</a>,
ovirt 3.6 was supposed to support the hot
plug memory feature. Nothing happens in
reality when increasing memory on a running
vm with centos7.<br class="">
I found this : <a moz-do-not-send="true" href="http://lists.ovirt.orgpipermail/kimchi-devel/2015-June/010714.html" rel="noreferrer" target="_blank" class="">http://lists.ovirt.orgpipermail/kimchi-devel/2015-June/010714.html</a>,
and it seems that el7.1 can't support the
feature because of its libvirt version
(1.2.8) while the required one is 1.2.14.<br class="">
I didn't test, but I guess F22 supports it.<br class="">
Is there any chance that el7.2 would support
it with a backported libvirtd?<br class="">

<div class="">It does support it, but only
hot-plug not hot-unplug.<br class="">

dedicated libvirt rhev package be released

qemu-kvm for live snapshot some time ago)?<br class="">
Documentation and limitation of the libvirt
version for hot plug memory are difficult to
find in the ovirt wiki and more generally on
the web.<br class="">
Maybe the feature has been postponed to a
3.6.z release?<br class="">
