	137	+= VM runtime setup =
	138	+
	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	+**qemu-guest-agent** is for allowing proxmox to query information from the VM such as IP address, shutdown commands, etc
	142	+
	143	+{{code language="bash"}}
	144	+sudo apt update
	145	+sudo apt upgrade -y
	146	+sudo apt install qemu-guest-agent -y
	147	+
	148	+sudo systemctl enable qemu-guest-agent.service
	149	+sudo systemctl start qemu-guest-agent.service
	150	+{{/code}}
	151	+
	152	+**reset machine-id** to not have overlapping ids from same templat
	153	+
	154	+{{code language="bash"}}
	155	+cat /dev/null > /etc/machine-id
	156	+cat /dev/null > /var/lib/dbus/machine-id
	157	+{{/code}}
	158	+
	159	+**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.
	160	+
	161	+

	169	+# from the distro configuration specified below

	171	+ - default
	172	+
