[ovirt-users] Can't boot VM: "At least one numa node has to be configured when enabling memory hotplug"

[gregor]

Hi,

yesterday I exported all my VM's and reinstalled the host fresh as
hosted-engine installation. After importing one VM and starting this, it
gaves me the error message (engine.log) see below.
After researching what "numa" means I don't have a clue what this should
mean or what was configured wrong. It's only one Server followed this
[1] instruction.
