"A snapshot is not immediately exported from vCenter to a mounted NFS share "
"and packaged into an OVA file format. This operation would consume time and "
"resources. Instead, the original file formats (e.g., VMDK) provided by "
"vCenter are retained. An OVA file will only be created as needed, on demand."
" To generate the OVA, CloudStack uses information in a properties file "
"(\\*.ova.meta) which it stored along with the original snapshot data."
