      The homepage welcome-screen on a 8.1.0 server point to download of XCP-ng Center 8.0.1.26.
      That xcp-ng-center version cannot connect to a 8.1 server.

      Thanks. I think that's because there's no officially stable release of XCP-ng Center out yet due do the fact that borzel is alone to maintain is and doesn't have time for it. Either there will be a stable release of the center before our final release, or we'll update the welcome page to point to the latest dev release (with a warning).

        We can also link the GitHub repo directly 🙂

            "Existing SRs are untouched (so remain formatted to EXT3)" How to convert existing Local storage? I upgraded to 8.1, but Local storage is Ext3.

              Quoting further:

              There is no easy way to convert an existing SR created with our driver, so those using it will need to move the VDIs out (to another SR or to export them), destroy the SR and create an EXT SR instead. Make sure to do this on XCP-ng 8.1.

              So is your question about how to create a SR and how to destroy one? What about Biggen's link shared above?

                  The link is not telling, how to change the Local Storage.
                  As far as I can see, Local Storage is not a partition like SR's on other physical disks.

                    mortenchristensn Local storage is an SR.

                    The commands below will remove the SR named "Local storage" and create a new one with the same name on the same device

                    If you have a pool with several hosts you need to run these commands on each host and, as stormi points out in the comment below, you need to move any VMs out of the Local SR before removing it.

                    # Get the IDs and device path to the current Local SR :
                    # xe host-list | grep -B1 $HOSTNAME | grep ^uuid| cut -d\: -f2 | cut -d" " -f2 > HostUuid.txt
                    # xe pbd-list sr-name-label=Local\ storage host-uuid=`cat HostUuid.txt` | grep sr-uuid | cut -d\: -f2 | cut -d" " -f2 > SR-Uuid.txt
                    # xe pbd-list sr-name-label=Local\ storage host-uuid=`cat HostUuid.txt` | grep ^uuid | cut -d\: -f2 | cut -d" " -f2 > Uuid.txt
                    # xe pbd-list sr-name-label=Local\ storage host-uuid=`cat HostUuid.txt` | grep device-config| cut -d\: -f3 | cut -d" " -f2 > Device.txt
                    # Unplug and destroy the Local SR : 
                    # xe pbd-unplug uuid=`cat Uuid.txt | egrep "*-*-*-*-*" `
                    # xe sr-forget uuid=`cat SR-Uuid.txt | egrep "*-*-*-*-*" `
                    # Create the new Local SR : 
                    # xe sr-create content-type=user device-config:device=`cat Device.txt` host-uuid=`cat HostUuid.txt` name-label=Local\ storage shared=false type=ext

                      Of course, move the VMs out of the SR before destroying it 🙂

                              How do you check exactly? (you haven't answered to Danp's "Where did you receive that output?")

                                  That's / and /var/log, not a local storage repository. Just read the other messages of this thread for a way to find the local SR and test its FS type.

                                    After an ISO upgrade to RC1 from 8.0 it booted... so that's good.

                                    Using XCP-ng Center 99.99.99.28:
                                    Changing "Control Domain Memory" does not take effect.
                                    SMB ISO fails "SM has thrown a generic python exception" for existing SR.
                                    I deleted the ISO SR and can't create a new one (same error):
                                    SMB ISO fails "SM has thrown a generic python exception" for new SR.

                                    Python errors at boot:

                                    I did not have the problems with 8.0.

                                    I had one VM that will no longer boot because of a missing disk. After attaching the disk there was a message about a PV error (it's not set for PV) and it still fails.

                                    As a test system there may have been some issues left over but it was all working with 8.0.

                                    So as a "production ready" upgrade. No.

                                      We do not support XCP-ng Center. The community as a whole can. Can you reproduce with other methods of changing dom0 memory? See https://support.citrix.com/article/CTX134951

                                      Does it work from Xen Orchestra? From command line using xe? Can you extract the errors at the time of the action from /var/log/SMlog, /var/log/daemon.log and /var/log/xensource.log?

                                      Where is that error seen? Is it visible directly in the console in place of XSConsole? It's like the value of cpu is a string instead of a dict. Weird.

                                      I've never seen upgrades detach disks from VMs. I suggest to open a separate thread for discussing and debugging the issue about this VM. Please give as much information as possible in that thread, including errors from logs (see https://github.com/xcp-ng/xcp/wiki/Logfiles).

                                        dariosplit I made a new 8.1-RC1 install and had the installer set up the Local SR as LVM.
                                        After the installation I ran the commands in my previous example and afterwards 'mount' and 'file -sL' show that it's ext4.

                                        HOWEVER; xsconsole still claims "Type : Ext3" so the console seems to have hard coded that "ext = ext3".
                                        Something for RC2 sort out.

                                          I like XCP-ng better... but I use XO too. The both have different advantages and issues.

                                          Using xen-cmdline --set-xen dom0_mem changes the grub.cfg entries EXCEPT the default (first) kernel-alt entry. So yes, it works, but not for the alt kernel install. Not the end of the world, I can edit the file and move on. But, should it modify all xen config lines or just the default/first one?

                                          I am able to create the SMB ISO SR using XO. The big issue is the old one (that I deleted) worked in 8.0 but did not work after the upgrade. Not a big deal the recreate it, but not good for an upgrade. There is some compatibility issue behind the scenes that now fails where it did not before.

                                          It looks like XCP-ng Center created the SMB ISO SR as a guest login without a username/password (empty/blank). Adding "guest/guest" in XO seems to resolve the problem. The issue is it worked before in 8.0 but not in 8.1.

                                          The errors at boot are seen in the console after boot and login prompt but before the XSConsole screen.

                                          As for the disk problem... I have been messing around a LOT with everything (local storage, iscsi, 7.6, 8.0, and back). I'm would not be happy to see these strange these strange things in a production system but I have been messing with the hosts in the lab more than a normal setup.

                                          I'm new to XCP and trying to help the community so I can benefit from improved software too.

                                            That is a very important information: you are using the alternate kernel (on purpose, I suppose? The installer is not supposed to make it the default kernel for you). Pinging r1 to take your feedback into account and debug.
