Virtuozzo Virtualization SDK C API Reference
Set custom storage URL.
A storage URL is required when actual data of a virtual hard disk is accessed using some external tool or protocol. For example, a VM disk backup, which resides on a remote server, could be attached as a data source using the following storage URL: "backup://backup_server/backup_UUID/disk_number". Here, instead of reading data from the locally stored disk image, a VM will connect to the "backup_server" and read data from the "backup_UUID/disk_number" backup.
