RAM: 32GB (reduced to 2048) NUMA enabled Hotplug CPU/Mem enabled Added for CPU: /lib/udev/rules.d/80-hotplug-cpu.rules SUBSYSTEM=="cpu", ACTION=="add", TEST=="online", ATTR{online}=="0", ATTR{online}="1" According to documentation, nothing else needs to be added for hot memory.

For IOMMU to work, you must add a PCI device image If you remove this device, the VM boots just fine and the above errors go away.
