      @r1

      @r1 our complete setup:

      [FreeNAS NFS] <----shared-storage----> [Pool of 2 servers (xen22 + xen23)] ----XAPI---> [XO from sources] -----remote----> [FreeNAS NFS]

      All [servers] are real hardware servers, no VMs involved.

      Same chain of servers for xen19, execpt there are more pool members (and VMs).

      @stormi I'm not complete sure if I did the iso upgrade or not... 😕

      But it's a good idea to reinstall the poolmaster from scratch...

      Good news from the kernel-alt (server xen19): No RAM leaks so far 🙂

      @stormi on server xen19 I think so, on server xen22 I'm not sure

      I looked more close on my memory graphs and saw, that the memory baseline increases every night:

      "bump" every day:
      ca76f2fc-89aa-49fb-aa33-5e568070fbc4-grafik.png

      closer look in week 53:

      Our Backups run from 18.00 till 3 or 4 in the morning (including coalesce).

      --> maybe the heavy IO load leads to memory leaks "somewhere"?

      @r1 yes, ever line "installed" in yum.log is an Upgrade from XCP-ng.
      Problems started with XCP-ng 8.x

      @r1 in general we do not restart many of our VMs, its all very static, only manual operated

      xen19 is now rebootet (we need it in production) with kernel-alt - highest id is currently 4

      xen22 (pool master of another affected pool) - highest id is curently 30

    • RE: Alert: Control Domain Memory Usage

      I noticed in my monitoring graphs, that since we have this issue, the SWAP is not used like before the issue:

    • RE: Alert: Control Domain Memory Usage

      We also have an issue with growing control domain memory:

      • XCP-ng 8.2
      • NFS shared storage
      • the poolmaster (xen19 is one of them) are more affected than pool members

      d1fac6d1-997b-4a7c-898c-d4a9c398b566-grafik.png

      Today I install the alternate kernel on one of our poolmaster to see if that resolves our issue.

    • RE: XCP-ng Center 20.03.00 released

      So it's clear to me (as thinking of inside Center): it is not a "template", so the snapshot is not working in the VM creation wizard. That's also the case with XOA snaps from backups, you can not create a VM from that in Center.. I always wondered about that, but as you found the flag it seems clear to me.

      We could fix it in two ways:

      • let Center create VMs from also from snapshot that are not "a template"
      • don't show the menu entry in Center on the snapshot list if it is not "is-template"

      I wonder why this flag is important, what was the reason to program Center this way 🤔

    • RE: [WARNING] XCP-ng Center shows wrong CITRIX updates for XCP-ng Servers - DO NOT APPLY - Fix released

      I just endet up to remove all URLs with "citrix." in them, except for XML-Namespaces which are not executed as download.

      I have big hopes for a new major XO(A) release to replace XCP-ng Center with a hopefull spectecular good way of a tree view 🎄
