 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
=20
 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
=E2=80=98memory'

was the VM started in a 3.6 cluster?=20
Or how/when did you create it?

Thanks,
michal

 I tried to restart vdsmd but it is the same, even on other hosts.
