139	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	140
141		-qemu-guest-agent is for
	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:

	143	+{{code language="bash"}}
	144	+unset HISTFILE
	145	+export HISTSIZE=0
	146	+export HISTFILESIZE=0
	147	+
	148	+sudo rm /.bash_history
	149	+rm ~/.bash_history
	150	+{{/code}}
	151	+
	152	+**qemu-guest-agent** is for allowing proxmox to query information from the VM such as IP address, shutdown commands, etc
	153	+
	154	+{{code language="bash"}}
	155	+sudo apt update
	156	+sudo apt upgrade -y
	157	+sudo apt install qemu-guest-agent -y

	160	+sudo systemctl start qemu-guest-agent.service

	163	+**reset machine-id** to not have overlapping ids from same template

	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.
	171	+
	172	+If you used a cloud-init base image it will have run the default cloudinit which installs and configures a bunch of systems.
	173	+
	174	+{{code language="bash"}}

	185	+# from the distro configuration specified below
