Hi again, There is no new memory banks created, example : before adding memory to the Cento7.2 VM I have 4 directories under /sys/devices/system/memory
memory0 to memory3 and their status was online. I augmented the memory from 512 to 1024 the were no new memoryX added and I had the error mentioned above: VDSM Noveria command failed: unsupported configuration: unknown device type 'memory' Failed to hot set memory to VM ipaClient. Underlying error message: unsupported configuration: unknown device type 'memory' both for Centos6 and Centos7 I stopped the VM Centos7, I added augmented the memory again, then started the VM, now I have new memoryX directories under /sys/devices/system/memory memory4 to memory7 2016-02-01 15:17 GMT+01:00 Yaniv Dary <yd...@redhat.com>: > Try: > > 1.
