Hi Anil, 

I have checked on the code and it looks it is not possible to enable this feature for the guest. We are running kvm through libvirt and it support this option: http://libvirt.org/formatdomain.html 

It could be an interesting feature. may be by an option readed from the image properties. There is something similar here: https://review.openstack.org/#/c/65028/ . 

What do you think?

Is it possible to enable the hugepages in the guest OS for the VMs launched in OpenStack (with KVM hypervisor)? Specifically is it possible to pass the “-mem-path” option when invoking QEMU?
