Hi,

Note that /etc/init.d/qemu-kvm calls /usr/share/qemu/init/qemu-kvm-init
which mounts hugepages under /run/hugepages.

The /dev/hugepages mounts appears to be done by systemd. We should
probably better coordinate, but filesystems really shouldn't be mounted
under /dev and we won't do this in a way that sacrifices compatibility
with other inits.

For now, setting KVM_HUGEPAGES=1 in /etc/default/qemu-kvm should
enable /run/hugepages on boot
