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)=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.
