 *Prep*
 Install the base OS.
 Install all required apps
+    * openssh-server
 Install all required updates
+
+Shutdown guest
+    * virsh shotdown $guest-vm
+
+
+On the VM Host server make sure you have libgustsfs-tools
+
+```
+apt list --installed |grep -i libguestfs-tools
+```
+
+if its not there, install it.
+
+```
+sudo apt install libguestfs-tools
+```
+
+
+This step strips stuff that must be unique per VM (machine-id, SSH keys, etc.) from the *template*.
+
+```
+sudo virt-sysprep -d $guest-vm \
+  --operations machine-id,ssh-hostkeys,udev-persistent-net,logfiles,tmp-files
+```
+
+Your output should be similiar to the following:
+
+```
+sudo virt-sysprep -d Debian-Base   --operations machine-id,ssh-hostkeys,udev-persistent-net,logfiles,tmp-files
+[   0.0] Examining the guest ...
+[  17.4] Performing "logfiles" ...
+[  17.6] Performing "machine-id" ...
+[  17.6] Performing "ssh-hostkeys" ...
+[  17.6] Performing "tmp-files" ...
+[  17.6] Performing "udev-persistent-net" ...
+```
+
+The base is now ready to go.
+
+**Create Clone**
+
+sudo virt-clone --original $guest-vm \
+  --name guest-01 \
+  --auto-clone
+
+example
+
+```
+sudo virt-clone --original Debian-Base \
+  --name Node01 \
+  --auto-clone
+Allocating 'Node01.qcow2'                                                                                                                                                                                                 | 1.6 GB  00:00:03 ...
+
+Clone 'Node01' created successfully
+```
+
+Confirm your clones have been made

+**SSH Key Gen**
+After a fresh install we want to generate an SSH key pair (public and private)
+we can then use this key to ssh onto hosts without having to share passwords.
+
+On the new host
+
+```
+ssh-keygen -t ecdsa
+```
+
+You could add a -C for comment and then add your emaiul address but... meh
+
+
+Example 
+
+```
+~$ ssh-keygen -t ecdsa
+Generating public/private ecdsa key pair.
+Enter file in which to save the key (/home/luddie/.ssh/id_ecdsa):
+Created directory '/home/luddie/.ssh'.
+Enter passphrase for "/home/luddie/.ssh/id_ecdsa" (empty for no passphrase):
+Enter same passphrase again:
+Your identification has been saved in /home/luddie/.ssh/id_ecdsa
+Your public key has been saved in /home/luddie/.ssh/id_ecdsa.pub
+The key fingerprint is:
+SHA256:gA+5oVKPdtlG7JQC5pL3NQ+OokUK7WoosTevWBCd1E0 luddie@debian-base
+The key's randomart image is:
++---[ECDSA 256]---+
+|  +. oE          |
+| B o.+..         |
+|= 1 * X          |
+|.O = / =         |
+|B = B * S        |
+|.X o .           |
+|*.+              |
+|o+ o             |
+|. ...            |
++----[SHA256]-----+
+~$
+
+```
+
+This will generate 2 keys in the .ssh folder
+
+```
+~/.ssh$ ls
+id_ecdsa  id_ecdsa.pub
+~/.ssh$
+```
+
+Use can then cat the .pub file to get the public keyu for that host, which can be added to the authorized_host file of other machines to gain access.
+
+You can also create an authorized_keys on your cost, and add other ssh pub key to allow them to have direct access to this host.
