    @Cygace Someone from the community may jump in and help troubleshoot this. The best approach would be to not modify the Dom0 installation by installing Zabbix via a community post, as you're customizing the installation. The vates team and XCP-ng specifically need to include these packages to ensure you're able to get support. Best of luck

    @Berrick Ah cool, I was anticipating that doing it live would've caused boot issues but I think I've just got a bug in my head about how it actually works, I'm conflating two separate things based on an incorrect interpretation of a previous experience I had once with XCP. Thanks!

    Sadly, it's hard to know what happened without getting the errors you had (eg when you tell: "VM will not start" is very vague).

    You can't add a host into another pool until it's "blank". It's hard to "merge" two pools together. So first, migrate VMs to the destination, clean the host and THEN add it to the pool.

    No need to update XCP-ng, we don't want to introduce a dedicated agent. It will rely on another mechanism. We'll publish about it before the end of this summer

    @geoffbland Hi, thanks for the reply... That's what I wound up doing, installing XO from source on a Raspberry PI that I had. I used it to restore my XO image from backup, once I did that I had to restore all of my guests (12 of them total). I could never figure out how to get my SR out of maintenance mode, so I wound up creating a new SR and restored each backup to the new SR. All back to normal after restoring the backup. Thank god XO backup works so well! I learned the hard way that I need to move my XO disks to local storage before I enter maintenance mode for my iSCSI SR... Oh well, lesson learned!

    @pdonias said in Netbox Plugin Enhancements: Why do you have those interfaces? Could you explain your use case and why they're not visible in XO? Sorry, you're right, hosts are not synced for a simple reason: there is no such thing as host types in Netbox (or did we miss something?). So we only group VMs by pools (clusters) and that's it. Those interfaces are for example wireguard interfaces or any other virtual interfaces. Obv they are not in xo because they are virtual, but in netbox they are needed because I deploy all my wireguard stuff with them. The host thing already was answered, there are devices which you then can link to Pools. KR Peter
