-   Deploy an Instance using the Template created above. Optionally, provide the detail `vm_name` to specify the name of the VM in Proxmox.
-   Otherwise, the CloudStack Instance's internal name is used. The VM Id in Proxmox is mapped to the CloudStack Instance and stored as a detail in CloudStack DB.

+   The VM Id in Proxmox is mapped to the CloudStack Instance and stored as a detail in CloudStack DB.
+   The Instance is provisioned on a randomly selected Proxmox host. The VM is configured with the MAC address and VLAN ID as defined in CloudStack.
+
+   The following external details can be provided optionally, while deploying the Instance:
+
+   * **vm_name**: Name of the VM in Proxmox. Default: *CloudStack Instance's internal name*.
+   * **storage**: Name of the storage in Proxmox to use for the VM's disk. Default: *local-lvm*.
+   * **is_full_clone**: Whether to create a full clone of the template (true) or a linked clone (false). Default: *false*.
+   * **iso_os_type**: Specify guest operating system if deploying from ISO. This is used to enable special optimization/features for specific operating systems. Valid values are: other | wxp | w2k | w2k3 | w2k8 | wvista | win7 | win8 | win10 | win11 | l24 | l26 | solarisOS. Default: *l26*
+   * **disk_size_gb**: Size of the disk in GB if deploying from ISO. Default: *64*.

 #. **Lifecycle Operations**
 
    Operations **Start**, **Stop**, **Reboot**, and **Delete** can be performed on the Instance from CloudStack.
