    @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!

    The initial job will take some time, but it will be fine after that. You can modify the job after getting your second or third run, to see how much data between each run is generated

    I'm not an English native speaker, it wasn't meant to be passive aggressive at all. I just told you that @julien-f already explained the initial reasons (also telling you we are aware of that fact). Also, XO 6 work is a major rework of the whole thing, and this will be taken into account on our redesign. A note, however: if someone can slip into your XOA, password, tokens and XAPI access are available in memory (regardless the fact you have encryption or not). In that case, a passphrase won't change anything. That's why we decided to remove any default password in the XO virtual Appliance template, so nobody still use default creds as a "known" entry point. And finally, as Xen Orchestra is fully Open Source, your contributions are very welcome

    @sidsanders Hi, I gave a look at your issue, it seems that it is often associated with the ssl certificate missing the middle of the Merkle chain. here are a couple of explanations: https://serverfault.com/questions/693033/unable-to-use-builtin-ca-bundle-to-verify-godaddy-sha2-ssl-certificate https://www.npmjs.com/package/ssl-root-cas I suspect that the certificate you gave to minio was incomplete. Note that the chain of certificate should not include the root certificate, only all the certificates in the chain minus the root. Nico.

    @dr4s1l-0 @Dr4s1l-0 you will not see the config drive mounted in your system, cloud-init only mounts it temporarily very early on in the boot process, copies the found config files off of it, and unmounts it. Mounting it manually will just cause more issues. You can probably see it being mounted early on in the logs in /var/log/cloud-init.log Cloud-init has introduced a ton of bugs this year and has no documentation regarding them, it has been a nightmare to try and track down these issues - I have a support customer with the same issue on recent versions of ubuntu and I've gotten nowhere. At this point I think it's best to take it up with the upstream project, cloud-init - from the XOA/XCP perspective we're doing everything we can, resulting in presenting a properly configured config drive - any issue after that is the cloud-init package
