Re: [ovirt-users] [FC22] testing oVirt 3.6.2 : Hot plug memory not working

Hi, I tried with the Centos6x64 VM, I didn't work, in ovirt's webui I have this error : VDSM Noveria command failed: unsupported configuration: unknown device type 'memory' Failed to hot set memory to VM mail10. Underlying error message: unsupported configuration: unknown device type 'memory' Looking into /sys/devices/system/memory there is no new memory banks added. But, I tested with another VM, Centos7x64 which I updated with latest packages : CentOS Linux release 7.2.1511 (Core) I tried to add memory, but I had the same error on ovirt's webui, I did not work neither with el6x64 or el7x64 and /sys/devices/system/memory didn't change, there are no new entries Regards 2016-02-01 10:30 GMT+01:00 Nathanaël Blanchet <blanchet(a)abes.fr&gt;: > Hi, > > the hot add features starts working out of the box from centos 7.2 guest. > On previous el7.x, two ways to do that: > > 5.2.
