When no DHCP server is available, or where creating a scope large enough for X-Ray VMs is not possible, use zero-configuration for self-assigned IP addressing.


Zero-configuration networking is a standard for IP addressing where a host self-assigns an IP address. X-Ray uses IPv4. which uses the reserved addresses


This feature eliminates the need for manual IP address configuration or DHCP.




To use zero-configuration networking, configure the workload VMs and the second NIC of the deployed X-Ray VM to use the same layer-2 network.


For ESXi, the .ova adds the second NIC automatically. For AHV, add the second NIC manually. The second NIC automatically picks up the zero-configuration settings when you add it, so no extra configuration is necessary.


Enabling IPMI Discovery on ESXi


Enable web-based enterprise management (WBEM) for IPMI discovery on ESXi


  • On ESXi 6.5, the IPMI discovery process is disabled by default, which results in unsuccessful connections during target creation.

  • If you do not have WBEM enabled, enable WBEM and then retry IPMI discovery. Otherwise, enter the IPMI data manually during X-Ray  target creation.

  • X-Ray supports the following ESXi versions for IPMI discovery.

    • vSphere ESXi 6.7

    • vSphere ESXi 6.5

    • vSphere ESXi 6.0

    • vSphere ESXi 5.5

    • vSphere ESXi 5.1

    • vSphere ESXi 5.0

  • If you have third-party CIM provider vsphere installation bundles (VIB) installed, WBEM services run automatically.




Connect WBEM as a root user on each ESXi host.


  • Run the following command on each ESXi host.

    • esxcli system wbem set --enable true

  • To verify that WBEM enabling was successful, use the following command.

    • esxcli system wbem get
