    @andrewperry Hi, we are working on 2 thinks: a proper fix under development to avoid new issue where snapshot-of field is garbage. a script to fix the wrongly set snapshot-of already present on affected pools. Both are necessary and we hope we can release the script soon to at least workaround if the issue happen again before we release the fix.

    @kratos said: This may not be best practice. in a two hosts pool, if your replicated VMs live on the Master, and it's gone, you won't be able to start the replicated VMs you will first need to transition slave to master indeed CR is better to another pool

    Version 1.4.0 is released: https://codeberg.org/NiXOA/system/releases/tag/v1.4.0 It includes significant changes and improvements, including: dedicated getting started section, migration to valkey, only needing to clone system, and helper scripts. the xen-orchestra-ce nixpkg now references the libvhdi nixpkg, and the core flake now references and pulls from the xen-orchestra-ce repo as an overlay. System (the user input flake) now uses the Core repo as an overlay, reducing the need to clone both locally AND allowing system to pull new updates and releases from core. XO, and libvhdi as needed. The next goal is: Make an xsconsole-like TUI Automate package updates for libvhdi and xen-orchestra-ce using CI/CD pipelines Submit libvhdi and xen-orchestra-ce as official nixpkgs

    Hello everyone. I tripped over this issue. If someone got another approach I would be interested. Thanks to @lsouai-vates I had a look at: https://github.com/vatesfr/xen-orchestra/blob/ab56924b1d046ccf6c09dfe7a4ab47deb5d77f4a/packages/xo-acl-resolver/index.js and https://github.com/vatesfr/xen-orchestra/blob/ab56924b1d046ccf6c09dfe7a4ab47deb5d77f4a/packages/xo-server/src/xo-mixins/acls.mjs#L150-L168 To what I understand it is not possible as a Non-Admin user to get information like pools, ... By creating a new admin user limiting the resources via ACLS with viewer right worked around this. However, granting admin rights still looks sort of strange. Just in case someone struggled as well this information might help.

    Installation: expecting an rsa key, any plans to support elliptic curve keys?

    @jivanpal We do not currently have any plans to support elliptic curve keys - this is a very sensitive topic given different governmental security requirements around the world. Note that Let's Encrypt recommends a dual setup for this exact reason: "Our recommendation is to serve a dual-cert config, offering an RSA certificate by default, and a (much smaller) ECDSA certificate to those clients that indicate support." (https://letsencrypt.org/docs/integration-guide/)

    @kagbasi-ngc Hi, thanks for your thoughts. I get on well with Linux myself - I’m using XO from source following the documentation, and actually, Ronivay’s script, as you mentioned, makes it all even handier. Still, I can’t help but think - your average home user, a total amateur, is just going to land on the XCP-ng host homepage and click "Deploy XOA". And then they’ve no backup, outside of the trial period. But sure, if XOA is aimed squarely at business and enterprise users with paid licences, fair enough that makes perfect sense. I just feel like backup isn’t really a purely business or enterprise feature, unlike, say, proxy instances or hyper-converged storage. It's something even home users would genuinely benefit from. But as it is mentioned above, that’s just how it’s set up - and like you said yourself, everyone’s got the chance to learn something new. And sure, in the age of AI chatbots, there’s really no excuse not to manage it

    @DustinB Been using it since 2012, non-profits fell under the academic tier and it was originally by number of cpu which was 2 cpu per host, under 192G ram but again didnt include vmotion etc, just plain ole esxi why I used Veeam since it brought replication into the mix again still using them at a very low cost. They had essentials and essentials plus and the academic pricing was very low, my understanding is they would rather you use VMware vs something else. Again I have receipts going back to 2012, pretty much same price for all these years until Broadcom entered the picture. There was nothing sus about it, you had to verify your non-profit category and fit within the limts, it was pretty standard pricing for a low number of cores, I could go to CDW or any reseller and get the same pricing. Why you have so many small companies jumping ship many were using vmware essentials which was WAY cheaper then what they are doing now which the only option is Standard and it now requires min of 16 cores per host @$50/core. That is the new and wonderful world of Broadcom... Anyway, this was pretty common stuff under VMware, why so many folks were using it, even the small shops.

    @RS One option would be this, assuming in this se you want to run the job at midnight on Dec. 25: /bin/echo "/path/to/your/script.sh" | at midnight Dec 25 While cron doesn't offer a specific one-time execution, you could also do this in cron but would have to remove the entry afterwards: 0 0 25 12 * /path/to/your/script.sh Also, take a look at this option: https://www.fastcron.com/guides/one-time-cronjobs/

    Olivier, I can say it's worse without the VGA being selected to 16Mb. That option is pretty much a must for any desktop virtualization. The novelty for me is people get far above 1080...

    @olivierlambert Thank you for your response. I have followed most of the documentation on setting up HA, and made sure that I have 3 hosts. All are Dell 7090 64GB RAM with 2 dedicated HA NICS. XCP-ng 8.3 is patched, XO is up to date, Xen tools 9.4.0 on all Windows VMs, and using the Xen tools ISO that can be mounted. eth0 1Gbs management network eth1 10Gbs iSCSI network DAC eth2 10Gbs VLAN Trunk, including backup network eth3 1Gbs HA eth4 1Gbs HA Overall, XCP-ng and XO are doing an excellent job. I feel like I am on an Easter egg hunt when pouring through documentation, but that is mostly my problem, because I see that you have put a lot of effort into organizing and updating it. My "use case" is replacing the VMware ESXi/vSphere 2-node cluster with XCP-ng and XO at the small high school (non-profit) where I volunteer as the IT guy. I feel that I am at the point where I trust XCP-ng and XO enough to make the switch during the summer break. Sorry to run on. The yellow triangles behind the non-master hostnames are just a small nuisance. I do notice that the hosts are hard to shutdown. Sending a shutdown command from either XO or from the host console causes a host to reboot, but not shutdown, even after having previously entered maintenance mode. I feel that this is not a big issue, just another small nuisance. The XO cluster is maintaining the integrity of the guest VMs. I will be reading all of the documentation I can, and upgrading to 8.4 when it is available. Thank you for supporting your awesome hypervisor.

    The plugin was initially created to check RAID created during install, not custom RAIDs created manually. But that could be an improvement to the plugin @stormi I leave you the honor to add this somewhere
