How to enable huge pages on a Ubuntu 18.04 VM hosted on a Windows 10 machine?

Question

I want to enable the use of huge pages on my Ubuntu 18.04 VirtualBox VM

• Host OS: Windows 10
• Host Memory: 16GB
• VM Memory: 8GB
• Huge Page Size = 2048KB

I've tried the following commands according to https://help.ubuntu.com/community/KVM%20-%20Using%20Hugepages

I added this to /etc/sysctl.conf

vm.nr_hugepages = 1024

However, the output of

cat /proc/meminfo | grep Huge

still shows

ShmemHugePages:    0 kB

My questions are

• Is there any configuration I need to do in my Windows host system to use huge pages?
• How do I enable the use of huge pages for my VM?
• How do I check if the target application in my VM is using the huge pages?
