- List all supported operations (enabled operations are indicated with asterisks):

`virt-sysprep --list-operations`

- Run all enabled operations but don't actually apply the changes:

`virt-sysprep --domain {{vm_name}} --dry-run`

- Run only the specified operations:

`virt-sysprep --domain {{vm_name}} --operations {{operation1,operation2,...}}`

- Generate a new `/etc/machine-id` file and enable customizations to be able to change the host name to avoid network conflicts:

`virt-sysprep --domain {{vm_name}} --enable {{customizations}} --hostname {{host_name}} --operation {{machine-id}}`
