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:
142 +
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
158 +
159 +sudo systemctl enable qemu-guest-agent.service
160 +sudo systemctl start qemu-guest-agent.service
161 +{{/code}}
162 +
163 +**reset machine-id** to not have overlapping ids from same template
164 +
165 +{{code language="bash"}}
166 +cat /dev/null > /etc/machine-id
167 +cat /dev/null > /var/lib/dbus/machine-id
168 +{{/code}}
169 +
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 +{{code language="bash"}}
173 +cloud-init clean
