139 +After creating the VM and before making it into a template there are some programs and settings we want to ensure exists always.
140 +
141 +(% id="cke_bm_721114S" style="display:none" %)** **(%%)**clear bash history** to not leave any configuration in history, clear and disable history file before proceeding:

146 +export HISTFILESIZE=0
147 +

150 +{{/code}}
151 +
152 +**qemu-guest-agent** is for allowing proxmox to query information from the VM such as IP address, shutdown commands, etc

155 +sudo apt update
156 +sudo apt upgrade -y
157 +sudo apt install qemu-guest-agent -y

168 +{{/code}}

170 +**cloud-init** is a great hook for installing or configuring programs or receiving variables from cloudinit CDROM drive. Making it easier to change IP, hostname, DNS, username/password, etc between VMs.
