    • RE: Change default filter in VMs list from current "power_state:running"

      @bullerwins

      It's a wonderful feature, you can have customized filters for VM, storage, Templates, and Pools. Combine that with using lots of tags and it makes larger deployments very manageable.

      @MichaelCropper
      I recently did a video tutorial on how XCP-NG virtual machine dynamic memory management and over allocation works.

    • RE: XCP-ng 8.3 public alpha 🚀

      @olivierlambert

      This was a full backup not a delta so that makes sense. I think I need more of my lab servers to be on 8.3 so I can do some more testing. I did not find any issues and nothing broke using it so I need to try harder. 😉

    • RE: XCP-ng 8.3 public alpha 🚀

      I did some testing with the 8.3 and it all went smooth except for one thing. We did a backup of a VM on 8.3 and if we try and restore it to version 8.2 I get the error

      "IMPORT_INCOMPATIBLE_VERSION"
      

      which makes sense and it's just a lab system so nothing critical. Is there a way to bring it back to 8.2 or should I update the rest of my lab to 8.3? 🙂

    • RE: Netdata package is now available in XCP-ng

      @Danp Thanks, that makes sense. Perhaps is should show "Premium Feature" instead of "netdata plugin is necessary" when using the free versions.

    • RE: Forgot password for the webgui

      @isener

      I think the XO-CLI has to be registered with XO to get it working and seeing as you are locked out that is not an option. Maybe someone here will offer a way to edit the database if not I would just delete and rebuild XO.

    • RE: Restoring Full Backup Error: Stream_vdi.Invalid_checksum

      @florent

      No encryption on this remote. And if I have time before I leave I will test importing the XVA with CLI and see what error I get.

    • RE: Delta Backup Showing Success No Delta Saved

      @AlexanderK This occurs on Synology as well. Without any corresponding errors coming from the TrueNAS target regarding permissions I don't see this as the same bug. It's also not occurring consistently so there is some combination of conditions that has to occur for this bug to trigger which is why I am testing so much.

    • Enable NBD Backups for a network

      I am running xo-server 5.109.0 & xo-web 5.111.0 and I have enabled NBD from the UI and verified that the parameter is showing on that network. This is the network on which XO is talking to XCP-NG .

      xe network-param-list uuid=12eaf1ae-9596-723e-a534-4d5a101ec4b4

      uuid ( RO)                    : 12eaf1ae-9596-723e-a534-4d5a101ec4b4

          default-locking-mode ( RW): unlocked
                       purpose (SRW): nbd
      
      

      I know I also have to be using the multiple data blocks on for the backup repository but I do have a few other questions:

      • Because the NBD option is now in the XO UI do I still need to edit the XO config.toml file & restart XO to enable or is that automatic?
      • Are there any firewall changes on the XCP-NG host or does this work over 443?
      • Does it matter if XO is running in another pool?
      • In the Xen Orchestra 5.76 Blog Post it was mentioned the "Lock" in the new "NBD" row which I see but is there some change I need to make?

    • RE: XCP / XO and Truenas Scale or Core

      @mauzilla
      Just an FYI, I have not tested the latest Scale 22.12 RC1 for performance but the previous versions of scale under some conditions was quite a bit slower. I have a video covering this topic here with the benchmarks and methodology used for testing.

    • RE: Delta Backups deleting .vhd files during merge operation

      @Gheppy

      The current version of TrueNAS-13.0-U3.1 has been stable for me, but this issue has persisted when doing Delta backups with SMB
      & TrueNAS, even older versions.
      https://xcp-ng.org/forum/topic/6148/delta-backup-showing-success-no-delta-saved

      My resolution to the issue was to move the backups over to NFS and they work well. Also, since I am using the newer "Store backup as multiple data blocks instead of a whole VHD file" option NFS is generally a bit faster with handling small files.
