all,<br class="">
<br class="">
I may miss something but according to <a moz-do-not-send="true" href="http://www.ovirt.org/Features/Hot_Plug_Memory" rel="noreferrer" target="_blank" class=""></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="">

Or will a dedicated libvirt rhev package be released
so as the downstream to support it (like 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="">
