A set of (meta-)Templates to create KubeVirt VMs.
This repository provides VM templates in the form compatible with OpenShift templates and OpenShift Cluster Console Web UI and those can further be transformed into regular objects for use with plain Kubernetes.
The VM templates are generated from meta-templates via Ansible and libosinfo. The generated templates are parametrized according to three aspects: the guest OS, the workload type and the size. The generated content is stored in dist/.
The Ansible playbook generate-templates.yaml describes all combinations that should be generated.
Every template consists of a VirtualMachine definition which can be used to launch the guest, if a disk image is available (see below).
Is it necessary to install the following components to be able to run the Ansible generator and the CI suite:
- jq
- ansible >= 2.4
- libosinfo
- python-gobject
- osinfo-db-tools
- intltool
By default the process below takes a generated template and converts it to an VM object that can be used to start a virtual machine.

# Build osinfo database
$ make -C osinfo-db
# Generate the template matrix
$ ansible-playbook generate-templates.yaml
# Pick a template by selecting
# - the guest OS - windows
# - the workload type - desktop
# - the size - medium
# Use the template

$The table below lists the guest operating systems that are covered by the templates. The meta-templates are not directly consumable, please use the generator to prepare the properly parametrized templates first.
Note: The templates are tuned for a specific guest version, but is often usable with different versions as well, i.e. the Fedora 34 template is also usable with Fedora 35.
