      @john-c

      Can you try installing ipv4 only and alternatively ipv6 only to see if it works ?
      (Just wanted to confirm something)

      @stormi @gb-123 When I tried installing as IPv4 only it was OK and came up correctly successfully. About to try IPv6 only will report back.

        @stormi @gb-123 When I tried installing as IPv6 only its currently trying to bring up the management network.

        EDIT - Update its still trying to bring up the connection with no success.

          @stormi @gb-123 Just done a reboot from maintenance mode, to see if this gets it to bring up the IPv6 only management network.

          UPDATE: Definitely didn't help still trying to bring up the IPv6 only management network.

            @stormi @gb-123 The issue with management network being brought up on XCP-ng 8.3 beta1, dual stack (IPv4 and IPv6). Specifically it taking a really long time or not coming up at all, likely is due to the IPv6 side not completing successfully or in a reasonable timespan.

            As shown by the problem on the IPv6 only install.

                @john-c hi thx for the feedback.

                How did you configure the IPv6 at install? Static, DHCP, autoconf?

                  It was configured on the IPv6 at install for DHCP as allocates IP addresses from its pool. I can have it done using Autoconf for more data if required.

                  If requiring static based testing will require a period to figure out what the static IP will be so that it jives successfully with the router's pool.

                    @john-c yes please try autoconf.

                    DHCP can be erratic in IPv6 i've found out. And so we might have still issue with in dom0.

                      @BenjiReis I'll test IPv6 using Autoconf then, though the DHCP does need some work to better handle its erratic nature. Given your admission in an earlier post, so that way there's less of an issue with the method of obtaining an IPv6 address.

                      Especially if it's the method of obtaining an IPv6 address for dom0!! Also worth considering whether or not to switch dom0 to obtaining its IPv6 address by Autoconf instead, if its more rock solid.

                      Anyway it most definitely definitely needs work on DHCP client option as its the method of automatically configuring the DNS servers, when the IP address is obtained using Autoconf.

                        @BenjiReis Sorry but using Autoconf to obtain IPv6 was no good, it didn't obtain an IP address. Thus it also gets stuck and/or takes a really long time to finish the start up.

                        I in the end needed to manually mount up a flash drive to copy the log due to not having a network connection to SSH into via.

                        Hopefully the now finally uploaded log file will give you more than enough information to finally crack this IPv6 management network IP address problem. If you manage to come up with an update or fix please send me an ISO with it on to test.

                          @BenjiReis Also as a side note you can only select "DHCP" when on the "Configure Management Interface" option within the "Network and Management Interface" screen.

                          So Autoconf needs to be added to this section so it can also be configured after install.

                              Some additional puzzling info for the bug. Which I discovered by using "ip link" and "ip addr" commands - note xenbr0, though it doesn't register or complete finishing start up. Also the XO: Lite doesn't become available over the IP addresses.

                                @john-c It looks like you do have an IPv6 so the issue of start up might be related elsewhere no?

                                  @BenjiReis Yes it does have an IP address. Though it doesn't seem to have brought the connection up, as reporting as "UNKOWN" and should be "UP".

                                  It's also reporting in the log that its not able to find DNS PIF which is configured through DHCP.

                                  Do you want me to test it with a statically configured DNS but Autoconf IP?

                                      @BenjiReis Even if xenbr0 is stays in "UKNOWN" state in normal operation. It still doesn't discount the issue with the DHCP configured DNS servers.

                                      The DNS configuration is an important part of being able to communicate on networks, as it resolves hostnames to IP addresses.

                                      Thus if the script, any command and/or program runs any kind of checks on remote systems, such as pinging them for instance by domain name. Then it wouldn't be able to resolve them and would thus think the network is down.

                                      So the finishing start up may then proceed to hang if it doesn't receive a report that the network connection is in essence up (active), through ping report. No response from ping (100% loss) for instance.
