Agent ID is generated based on various parameters, such as security identifier (SID) and SMBIOS Universal Unique Identifier (UUID). A SMBIOS UUID is a 128-bit number used to uniquely identify a host.
When you clone a VDI image, make sure that the SMBIOS UUID changes on the following VDIs to avoid duplication of agent IDs:
VMware vCloud Director
For more information, see VMware Knowledge Base.
vCenter hosted ESXi Server
To get the SMBIOS UUID on a virtual host, execute the following command:
wmic csproduct get UUID
