all,<br>
<br>
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"><a class="moz-txt-link-freetext" href="http://www.ovirt.org/Features/Hot_Plug_Memory">http://www.ovirt.org/Features/Hot_Plug_Memory</a></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 moz-do-not-send="true"
href="http://lists.ovirt.orgpipermail/kimchi-devel/2015-June/010714.html"
rel="noreferrer" 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>

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

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>
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>

<div>I works with fedora and you can use it currently
with this feature.<br>

It works on centos too, qemu-kvm-ev 2.3 we distribute in ovirt
repo</blockquote>
Hello, no qemu-kvm-ev 2.3 is not enough:<br>
[root@fuji ~]# qemu-img --version<br>
qemu-img version 2.3.0 (qemu-kvm-ev-2.3.0-29.1.el7), Copyright (c)
2004-2008 Fabrice Bellard<br>
and<br>
vdsm-4.17.10.1-0.el7.centos.noarch<br>
<br>
I get this error message each time I try to hot add memory :<br>
Dec 9 11:18:00 fuji journal: unsupported configuration: unknown
device type 'memory'<br>
<br>
I tried to restart vdsmd but it is the same, even on other hosts.<br>
<br>
any help will be appreciated, thank you.<br>
