#sudo sysctl -w vm.nr_hugepages=2048
sysctl: cannot stat /proc/sys/vm/nr_hugepages: No such file or directory

# grep HUGETLB /boot/config-4.4.0-36-generic

Kernel supports hugepages.
Not enabled in KVM? Why?

Can you verify what kernel you're booted to?

$ uname -r

By default, Linodes boot to Linode-supplied kernels. I don't know if hugepages are enabled in Linode's kernel (its configuration is in /proc/config.gz if you wish to check). If you wish to boot to a kernel supplied by your distribution, you'll want to make some changes to your Linode's configuration profile as documented at ... -with-kvm/
