<br>
I may miss something but according
to <a href="http://www.ovirt.org/Features/Hot_Plug_Memory" target="_blank">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>
I found this : <a href="http://lists.ovirt.orgpipermail/kimchi-devel/2015-June/010714.html" rel="noreferrer" target="_blank"></a><a href="http://lists.ovirt.orgpipermail/kimchi-devel/2015-June/010714.html" target="_blank">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>
I didn't test, but I guess F22
supports it.<br>
Is there any chance that el7.2
would support it with a backported
libvirtd?<br>
</blockquote>
<div><br>
</div>
<div>It does support it,
but only hot-plug not hot-unplug.<br>

dedicated libvirt rhev package be
released so as the downstream to
support it (like qemu-kvm for live
snapshot some time ago)?<br>
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>
Maybe the feature has been
postponed to a 3.6.z release?<br>

was the VM started in a 3.6 cluster? <br>

sure, on a full 3.6 cluster. I stopped/restarted them. I
restarted vdsmd and libvirtd<br>

<div><br>
</div>
ok..and just for the sake of completeness - what is libvirt
version exactly? If you’re running <1.2.14 then your initial
comment make a lot of sense….</div>
<div>Yes, el7.2 has the right one (1.2.17) but even on 7.1 it
should support it and if it doesn’t it’s our problem we should
fix in ovirt (similarly as we solve qemu by shipping it
ourselves)<br>
