Background

While I'm learning how to use Nginx, I was instructed to update the server_names_hash_bucket_size (/etc/nginx/nginx.conf) value from 32 to 64, but I don't understand why should I increase the value to 64.

pf_enable="YES"

ifconfig_lo1="inet 172.16.1.1 netmask 255.255.255.0"

TL;DR

Create 10GB FreeBSD image using QEMU.
Run the VM using xhyve.
Mount host directory.
Resize the image.

FreeBSD Jails with VLAN HOWTO

This article discusses how to set up jails on a FreeBSD 11-CURRENT system utilizing VIMAGE (aka VNET) to provide a virtualized independent network stack for each jail with support for VLAN tagging.
