I've looked into this and hugepages is managed via KVM. Many distros automatically enable feasible hugepage moutpoints via qemu/KVM system configuration or systemd by default. For example, Ubuntu and Debian report Hugepagesize: 2048 kB by default.

Therefore adding hugepage management via quickemu is risky since it is will be possible to tread on pre-existing hugepage configuration.

Therefore, if you are using a distribution that doesn't enable hugepages by default, it is left as an exercise for the user to configure hugepage appropriately if so desired.
