then Hugepages aren't enabled.
To enable Hugepages first check <code>/etc/sysctl.conf</code> for the following entries:
<syntaxhighlight lang=text>
vm.nr_hugepages=
vm.hugetlb_shm_group=
</syntaxhighlight>
The general rule of thumb is 1 Hugepage for ever 2MB of of RAM to be passed through:
<syntaxhighlight lang=text>
vm.nr_hugepages=8192
vm.hugetlb_shm_group=48
</syntaxhighlight>
The above example will pass-through approx 16GB to the VM.
