        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:
          Traceback (most recent call last):
          File "/usr/lib64/xsconsole/XSConsole.py", line 46, in <module> main()
          File "/usr/lib64/xsconsole/XSConsole.py", line 37, in main app.Enter()
          File "/usr/lib64/xsconsole/XSConsoleTerm.py", line 57, in Enter Data.Inst(),Up
          date()
          File "/usr/lib64/xsconsole/XSConsoleData.py", line 343, in Update self.DeriveDa

          File "/usr/lib64/xsconsole/XSConsoleData.py", line 361, in DeriveData name = "
          ".join(cpu['modelname'].split()))
          TypeError: string indices must be integers, not str

          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.

            Thanks for the feedback.

            What's the output of uname -a?

            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

            SMB ISO fails "SM has thrown a generic python exception" for new SR.

            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?

            TypeError: string indices must be integers, not str

            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 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.

            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.

                    Yes, I installed the alt kernel and made it the default entry in grub.
                    I was trying to solve an IOMMU problem on an AMD system (that is unsolvable).

                    Also, I hope the microcode firmware gets updated as there are new hypervisor attacks with AMD CPUs. Yes, I know I can manually install an update but it seems more important to update it in a VM environment than on a single host. Maybe, at least, add it to testing.

                        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?

                        xen-cmdline utility will only update the base kernel XCP-NG and XCP-ng (Serial), all other including kernel-alt are for debug purpose hence not touched. The script is also inherited from Citrix so its kept as-is.

                        Regarding the SMB ISO SR, it looks like XAPI or XAPI DB might have lost username/password in upgrade, this can be checked further in relevant code base.

                        Regarding XSConsole, if you have ssh access to the host, try to run it manually by # xsconsole and share the full error stack to trace further.

                          The errors seem to be a boot time issue. When I run xsconsole from a shell I don't see the same errors.

                            If you have an XOA (any version) installed and can open a support tunnel, I'm willing to have a look at the issues as part of the RC phase.

                                @peder said in XCP-ng 8.1 Release Candidate now available!:

                                @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.

                                Now solved. Just run yum update, restart the xsconsole service, and it will display 'Ext' instead of 'Ext3'.

                                  @stormi Yes, that did it.
                                  I suppose there's currently no way to show the actual filesystem, instead of the generic "Ext", in the xsconsole?
                                  You have to resort to a shell and 'mount' or 'file -sL' to see that?

                                    @peder That would require more than just a simple fix indeed.

                                      I have pushed three new updates: kernel-alt, xcp-python-libs and xapi(-*).

                                      • kernel-alt updated to 4.19.108 by @r1
                                      • xcp-python-libs updated as a requirements for handling the grub configuration update when kernel-alt will be updated, now and in future updates
                                      • xapi updated with code by @BenjiReis to handle export and restore of VMs in a suspended state. This is a foundation for a future XO feature related to that.

                                      Please update and make sure that you notice no regression related to those updates.

                                          Rule of thumb:

                                          • if there's an update on a kernel you are using in the dom0, you must reboot to run on the updated kernel
                                          • if there's a Xen update, idem
                                          • if there's a XAPI update, in most case, toolstack restart is enough
                                          • for other thing, it's more variable and hard to predict. But let's say in general, no mandatory reboot. However I'd like to stress that rebooting is a good thing, especially for all security related updates.

                                            I'd add: if you don't reboot, always restart the toolstack. It's better to restart it for nothing than to forget to restart it. Note that the above Rule of thumb is also written in the updates howto.

                                            For precise instructions related to any update, refer to the blog post that announces them (until we can get them directly in XO). I try to always give such instructions. Forgot here because it's the RC.
