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
Hello, no qemu-kvm-ev 2.3 is not enough:
[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?
sure, on a full 3.6 cluster. I stopped/restarted them. I restarted vdsmd
and libvirtd
Or how/when did you create it?
those vms have been created before uprading to 3.6, some of them from a
blank template, other one based on a el7 template.
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
