[libvirt] [PATCH 2/2] qemu: Check for guest NUMA nodes properly when validating hugepages

[Michal Privoznik]

https://bugzilla.redhat.com/show_bug.cgi?id=1448149

In fa6bdf6afa878 and ec982f6d929f3c23 I've tried to forbid
configuring <hugepages/> for non-existent guest NUMA nodes.
However, the check was not fine tuned enough as it failed when no
guest NUMA was configured but <hugepages/> were configured for
guest NUMA node #0.
