When building the default memory backend (which has id='pc.ram') and no guest NUMA is configured then qemuBuildMemCommandLineMemoryDefaultBackend() is called. However, its return value is ignored which means that on invalid configuration (e.g. when non-existent hugepage size was requested) an error is reported into the logs but QEMU is started anyway. And while QEMU does error out its error message doesn't give much clue what's going on: qemu-system-x86_64: Memory backend 'pc.ram' not found While at it, introduce a test case. While I could chose a nice looking value (e.g. 4MiB) that's exactly what I wanted to avoid, because while such value might not be possible on x84_64 it may be possible on other arches (e.g. ppc is notoriously known for supporting wide range of HP sizes). Let's stick with obviously wrong value of 5MiB. Reported-by: Charles Polisher <chas@chasmo.org> Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Ján Tomko <jtomko@redhat.com>
