A participant on the Univention Summit 2020 asked for this:

1. Download UCS appliance image for KVM from <http://updates.software-univention.de/download/evaluation/UCS-KVM-Image.qcow2>
2. Start VM
3. Abort "Univention System Setup" (USS) running in Browser with "Ctrl-Q"
4. Login as user "root" with password "univention"
5. ucr set repository/online=yes repository/online/unmaintained=yes  # Bug #46294 comment 3
6. apt-get -qq update
7. apt-get install cloud-init
8. apt-get clean
8. dpkg-reconfigure cloud-init
   # Select the source most appropriate for your environment; see <https://cloudinit.readthedocs.io/en/latest/topics/datasources.html>; easiest is probably "NoCloud"
   # When using `univention-cloud-init` do this with UCRV system/setup/cloud-init/datasources=NoCloud,None
9. ucr set repository/online=no repository/online/unmaintained=no
10. ucr set system/setup/boot/start=no  # Disable starting USS in browser (automatically done by univention-cloud-init)
11. poweroff  # VM
12. Use this so prepared image as your new master image

For UCS there also is the UCS package `univention-cloud-init`, which provides the integration to run system setup from cloud-init:

1. apt install univention-cloud-init
2. Setup cloud-init to provide the file configuration as documented at <https://docs.software-univention.de/installation.html#appliance:use:cloudinit>
3. Run new VM with copy or copy-on-write-enabled base image

Further optimizations:
- ucr set grub/bootsplash=nosplash grub/quiet=no grub/rootdelay=0 grub/generate-menu-lst=no  # Disable splash and delays and enable debug output


Default values from univention-cloud-init:

ucs_setup:
 hostname: ucs
 domainname: ucs.local
 windowsdomain: UCS
 ldap_base: dc=ucs,dc=local
 rootpassword: univention
 role: domaincontroller_master
 components:
 package_install:
 package_remove:
 eth0_address: dhcp
 eth0_broadcast:
 eth0_netmask:
 eth0_network:
 nameserver:
 dnsforwarder:
 gateway:
 sslou: Univention Corporate Server
 sslorg: DE
 sslemail: ssl@ucs.local
 sslstate: DE
 ssllocality: DE
 timezone: America/New_York
 keymap: en_us

You can manually configure the network by setting "eth0_address" and "eth0_netmask" (and optionally "eth0_network" and "eth0_broadcast").

univention-cloud-init is deprecated and no longer supported.
