I use the ovirt-node, and I configured HUGEPAGE on the VM, and does not configure the HUGEPAGE on the KVM host.
The THP I don't configure anything about it, and after configure the HUGEPAGE on the vm, there is no report. I don't know which method is the best.

And if, after enabling/configuring hugepages in the VM, it is reporting hugepages are in use in the host?

The virtual machine is running database, which needs to set the memory huge page on the OPERATING system of the virtual machine. If I need to set the huge page on the VIRTUAL machine, do I also need to set huge page on the KVM physical machine? Or just on the virtual machine? What best practices do you recommend? Thank you very much!
