-==== NOT WORKING: Importing OVA file ==== 
-  * **Very slow method**, exporting OVA needs to copy all discs into exported and well compressed file. 
-  * In VirtualBox choose "**File**" --> **"Export Appliance"** 
-    * select to export all network cards and MAC addresses 
-  * Proxmox cannot import OVA files directly. Please unpack it with command <code bash>tar -xvf WIN7.ova</code> 
-    * After unpacking, manifest file .ovf will be available. 
-  * <code bash>qm importovf 701 ./WIN7.ovf local-zfs --dryrun --format qcow2</code> 
-    * WARNING: <code>warning: unable to parse the VM name in this OVF manifest, generating a default value</code>
