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

Hi all,
I may miss something but according to http://www.ovirt.org/Features/Hot_Plug_Memory, 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.
I found this : http://lists.ovirt.orgpipermail/kimchi-devel/2015-June/010714.html, 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.
I didn't test, but I guess F22 supports it.
Is there any chance that el7.2 would support it with a backported libvirtd?
It does support it, but only hot-plug not hot-unplug.
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)?
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.
Maybe the feature has been postponed to a 3.6.z release?
I works with fedora and you can use it currently with this feature.
It works on centos too, qemu-kvm-ev 2.3 we distribute in ovirt repo
[root@fuji ~]# qemu-img --version
qemu-img version 2.3.0 (qemu-kvm-ev-2.3.0-29.1.el7), Copyright (c) 2004-2008 Fabrice Bellard
and
vdsm-4.17.10.1-0.el7.centos.noarch
I get this error message each time I try to hot add memory :
Dec 9 11:18:00 fuji journal: unsupported configuration: unknown device type ‘memory'
was the VM started in a 3.6 cluster?
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….
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)
I'm really surprised that such a waited feature has not been yet tested by the community users with el7, so that nobody has reported the issue yet.
Weird indeed. Well, RHEL 7.2 is out for more than a month and there is centos 7.2 beta and perhaps rc as well, it's due very soonSandro, we should think about it - since we push qemu-kvm-ev we do not really enforce anyone to run on el7.2. We want to do that for various reasons as soon as possible. Maybe updating qemu-kvm-ev to require new 7.2 libvirt?
those vms have been created before uprading to 3.6, some of them from a blank template, other one based on a el7 template.Or how/when did you create it?
Thanks,michal
I tried to restart vdsmd but it is the same, even on other hosts.
any help will be appreciated, thank you.
Thank you for your help
