Re: [libvirt] [PATCH v2] qemuBuildMemPathStr: Forbid memoryBacking/access for non-numa case

https://bugzilla.redhat.com/show_bug.cgi?id=1448149 If a domain has no numa nodes, that means we don't put any memory-backend-file onto the qemu command line. That in turn means we can't set access='shared'. Therefore, we should produce an error instead of ignoring the setting silently.
