A few commits ago, in aeecbc87b73, I've implemented command line generation for ACPI HMAT. For this, we need to know if at least one guest NUMA node has vCPUs. This is tracked in @masterInitiator variable, which is initialized to -1, then we iterate through guest NUMA nodes and break the loop if we find a node with a vCPU. After the loop, if masterInitiator is still negative then no NUMA node has a vCPU and we error out. But this exact check was missing comparison for negativeness.
