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)=20
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=20
type 'memory'
I tried to restart vdsmd but it is the same, even on other hosts.
any help will be appreciated, thank you.

Documentation and limitation of the libvirt version
