      Hi Sunjay,

      Thank you for reporting this. The collision shouldn’t occur, I will look at this and will share updates on this soon.

      Thanks,

          Hi Prateek,

          We currently do not support guaranteed Quality of Service (QoS), but we do offer best-effort QoS. You can request bandwidth by setting it on your interfaces using a command like iface.set_bandwidth(10).

          Please note that Basic NICs are essentially Virtual Functions, and the underlying dedicated NIC is shared, so guaranteed bandwidth may not be achievable. However, you should see better performance with ConnectX_6 or ConnectX_5 NICs.

          Here’s an example slice request for your reference:


          #Create Slice
          slice = fablib.new_slice(name=slice_name)
          # Network
          net1 = slice.add_l2network(name=network_name, subnet=IPv4Network("192.168.1.0/24"))
          # Node1
          node1 = slice.add_node(name=node1_name, site=site)
          iface1 = node1.add_component(model='NIC_Basic', name='nic1').get_interfaces()[0]
          iface1.set_mode('auto')
          iface1.set_bandwidth(10)
          net1.add_interface(iface1)
          # Node2
          node2 = slice.add_node(name=node2_name, site=site)
          iface2 = node2.add_component(model='NIC_Basic', name='nic1').get_interfaces()[0]
          iface2.set_mode('auto')
          iface2.set_bandwidth(10)
          net1.add_interface(iface2)
          #Submit Slice Request
          slice.submit();

          Thanks,
          Komal

            Thank you, Prateek, for sharing your slice ID and observations! If you encounter this issue again, please let us know and refrain from deleting the slice. This will greatly assist us in debugging and identifying the problem.

            Unfortunately, we can’t do much with a deleted slice. We appreciate your cooperation with this!

            Thanks,

              Hi Sunjay,

              Are you still facing this issue? I tried a slice on TOKY and didn’t run into any access issues.

              Please let us know.

              Thanks,

                Hi Sunjay,

                I just checked all the VMs on your slice. I can ping all FabNetv4Ext IPs from my laptop. I’ll check with Network Team and share more details if we see any issues.

                Thanks,

                  Hi Nirmala,

                  This looks like a bug in fablib which doesn’t have the update regarding the username for default_kali. Could you please try using user kali to access the VM?

                  I will work to provide a fix for this soon. Apologies for the inconvenience!

                  Thanks,

                    Sorry for the confusion, Users can still validate their keys against the bastion host using the command above as indicated on the learn article.

                      Hi,

                      Could you please try running this notebook?

                      jupyter-examples-rel1.6.1/configure_and_validate.ipynb

                      This will validate your configuration and update it if needed.

                      Please try running the Hello Fabirc Notebook after that. This notebook creates a VM and also displays the SSH command to use to login into the VM. Please check if the SSH command works and let us know if the issue still persists.

                      NOTE: Bastion host is only used as a jump box, we do not allow login to Bastion Nodes.

                      Thanks,

                        The fix for this issue is now available with fabrictestbed-extensions==1.7.2

                          Hi Nishanth,

                          We just added support for users to query host level information as well. Examples for this would be available in a couple of days. I am sharing a snippet below on how this can be done:


                          fablib.list_hosts()
                          resources = fablib.get_resources()
                          site = resources.get_site("MAX")
                          all_hosts = site.get_hosts()
                          host = site.get_host(name="max-w1.fabric-testbed.net")
                          print(host)

                          Please checkout our documentation here to find more details. Please let us know if you have more questions/concerns.

                              Apologies for the inconvenience! I looked at your Slice and can confirm from the logs the deletion was triggered by user either via Fablib/Portal.

                              This possibly may have happened because of the Bug reported here With the maintenance next week the delete bug would be addressed.

                                Hi Nishant,

                                It appears that a network service has leaked. In a distributed system like our testbed, encountering some leaked resources is not unusual. We plan to deploy updates in the coming week to address this issue. In the meantime, I recommend introducing a delay between deletion and recreation, as the resources are distributed across the testbed.

                                For now, I have cleaned up the leaked services, so provisioning should work.

                                Also, if possible could you please share your notebook or code- snippet that might help reproduce this state. Would be super helpful to debug and address this issue? Appreciate your help with this!

                                Best regards,

                                Komal

                                  We are deploying 1.7 next week which would contain a fix for this issue. Apologies for the inconvenince!
