(Get the code!)
The "pages" element specifies the huge page size, so even if you don't need NUMA we still need the pages element, so that's not a bug. For NUMA, the system default allocation rule implemented by the kernel is just a preference, not a guarantee, so the actual placement of the guest is not going to match what the schedular is expecting. The NUMA code is complex enough without having to add workarounds for outdated versions of QEMU or versions which distros crippled. At most we should extend the version check here.
