Note: Each machine (physical or virtual) managed by DEX must have a unique SMBIOS UUID. DEX relies on the SMBIOS UUID to identify systems. If two machines share the same value, they cannot be distinguished and may be detected incorrectly. Ensure uniqueness by following your hardware or hypervisor vendor's guidelines (for example, HP, Apple, VMware) when provisioning, cloning, or replacing machines.
