hello i am on gentoo linux,
how do i tell qemu/libvirtd to use hugetlb?

hugetlb is activated in kernel.
i cant find any hints in man or docu on website.

a cat on meminfo show this:

AnonHugePages:   7272448 kB

HugePages_Rsvd:        0

Hugepagesize:       2048 kB

any ideas how to tell qemu / libvirtd to use hugetlb?

an KVM_HUGEPAGES=1 in the /etc/conf.d/libvirtd seems not activate it.

thanks for any help
