= Creating a VM from a VirtualMachine manifest
|
|
|
|
You can create a virtual machine (VM) from a `VirtualMachine` manifest. To simplify the creation of these manifests, you can use the `virtctl` command-line tool.
|
|
|
|
.Prerequisites
|
|
|
|
* You have installed the `virtctl` CLI.
|
|
* You have installed the {oc-first}.
|
|
|
|
.Procedure
|
|
|
|
. Create a `VirtualMachine` manifest for your VM and save it as a YAML file. For example, to create a minimal {op-system-base-full} VM, run the following command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ virtctl create vm --name rhel-9-minimal --volume-import type:ds,src:openshift-virtualization-os-images/rhel9
|
|
----
|
|
|
|
. Review the `VirtualMachine` manifest for your VM:

|
|
[NOTE]
|
|
====
|
|
This example manifest does not configure VM authentication.

. Create a virtual machine by using the manifest file:

$ oc create -f <vm_manifest_file>.yaml

----
|
|
$ virtctl start <vm_name>
