If memory-backend-{file,ram} has a size that's not aligned to underlying page size it is not only wasteful, but also may lead to hard to debug behaviour. For instance, in case memory-backend-file and hugepages, madvise() and mbind() fail. Rightfully so, page is the smallest unit they can work with. And even though an error is reported, the root cause it not very clear:qemu-system-x86_64: Couldn't set property 'dump' on 'memory-backend-file': Invalid argument After this commit: qemu-system-x86_64: backend 'memory-backend-file' memory size must be multiple of 2 MiB
