      I am running xo-server 5.109.0 & xo-web 5.111.0 and I have enabled NBD from the UI and verified that the parameter is showing on that network. This is the network on which XO is talking to XCP-NG .

      xe network-param-list uuid=12eaf1ae-9596-723e-a534-4d5a101ec4b4

      uuid ( RO)                    : 12eaf1ae-9596-723e-a534-4d5a101ec4b4
                    name-label ( RW): Dot3
              name-description ( RW): 
                     VIF-uuids (SRO): 66e895eb-b52a-a370-37a4-4bd74f299be0; 345ff1c0-0ea2-44dd-6308-07eabd75f770; 36072018-1e8b-03ea-a675-94c7b540e0e2
                     PIF-uuids (SRO): cc5f027f-cdf4-1e17-f393-51bf450c6855
                           MTU ( RW): 1500
                        bridge ( RO): xenbr3
                       managed ( RO): true
                  other-config (MRW): 
                         blobs ( RO): 
                          tags (SRW): 
          default-locking-mode ( RW): unlocked
                       purpose (SRW): nbd
      
      

      I know I also have to be using the multiple data blocks on for the backup repository but I do have a few other questions:

      • Because the NBD option is now in the XO UI do I still need to edit the XO config.toml file & restart XO to enable or is that automatic?
      • Are there any firewall changes on the XCP-NG host or does this work over 443?
      • Does it matter if XO is running in another pool?
      • In the Xen Orchestra 5.76 Blog Post it was mentioned the "Lock" in the new "NBD" row which I see but is there some change I need to make?

          hi @lawrencesystems

          You still need to enable it in config fr now. I hope we 'll be able to improve the ui to enable it on a per backup setting later

          The nbd protocol use the 10809 port in TCP by default. XO only read from this port f the host.

          The Nbd setting is used for the whole xo, regardeless of the pool

          The lock have been replaced by a select, which is more self explanatory . I think the main control pint is to check if there is multiple NBD network for a VM, XO use the first one returned by the Xapi, and it may be , for example, a managemet network as opposed to a backup / high speed one

          Regards
