vdsm supports dynamic allocation of Huge Pages, but https://access.redhat.com/solutions/4904441 indicates the issues in 4.3 related to hugepages (you can see the solution via RH dev subscription).If you needed to set them manually and everything works normally, I would have picked something like 90-95% in HugePages. Yet, due to the issues described in that solution - it's better to enable HugePages only in the Guest.
