XCP-ng 8.1 Release Candidate now available!



  • @peder Dosen't work. My version is 8.1 Build date: 2020-02-19 and reciveed the resoult " Name: Local storage Type: Ext3."



  • @dariosplit What exactly doesn't work? Where did you receive that output?



  • @Danp I got Ext3 again instead of Ext4.

    @Danp I got Ext3 again instead of Ext4.

    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:
    Traceback (most recent call last):

    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

    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 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.

    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.


  • XCP-ng Team

    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.



  • Upgraded my R620 to the RC. Noticed the following during the boot process, but it eventually loaded and seems to be functioning fine thus far --

    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?


  • XCP-ng Team

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