The past year 2022 was again an exciting year with numerous innovations in XCP-ng and Xen Orchestra as well as good and helpful discussions in the forum. I am excited about what the new year brings and wish everyone a good start for 2023.

A wonderful new year for everybody

RE: Can I just say thanks?
I second that! While not a commercial user, I really like the community and the active participation of the Vates team helping novice homelab user with patience and commercial user with in-depth knowledge alike. Keep rocking!

RE: Backup reports on Microsoft Teams
You could at least send the backup reports (requires
backup-reports
andtransport-email
plugin on XOA) to a Microsoft Teams channel of your choice (Channel - More options - Get email adress). -
RE: Updates announcements and testing
@gduperrey Updated my two host playlab without a problem. Installed and/or update guest tools (now reporting
7.30.0-11
) on some mainstream Linux distros worked as well as the usual VM operations in the pool. Looks good -
RE: Updates announcements and testing
@stormi Did not even know the problem existed . Anyway, added a new (second) DNS server (9.9.9.9) to the DNS server list via
xsconsole
and rebooted the host (XCP-ng 8.2.0 fully patched).Before update: DNS 9.9.9.9 did not persist, only the previous settings are shown
After update: DNS 9.9.9.9 did persist the reboot and is listed together with the previous settingsDeleting DNS 9.9.9.9 worked as well, so the
xsconsole
update worked for me. -
RE: Updates announcements and testing
@stormi Updated my two host playlab (8.2.0 fully patched, the third host currently serves as a Covid-19 homeoffice workstation) with no error. Rebooted and ran the usual tests (create, live migrate, copy and delete a linux and a windows 10 VM as well as create / revert snapshot (with/without ram) ). Fooled myself with a
VM_LACKS_FEATURE
error on the windows 10 VM until I realized that I forgot to install the Guest tools - I need more sleep. Will try a restore after tonights backup.Edit: restore from backup worked as well

A great and happy new year
A great and happy new year 2022 to everybody! Another year has passed and the XCP-ng community continues to rock! Stay optimistic and healthy (never hurts ).

RE: Updates announcements and testing
@stormi My two host cluster (HP ProDesk 600 G6) updated without an issue. Let's see how the cluster is performing during the coming days.

Updated my playlab and nothing to report. Looks good.

RE: Updates announcements and testing
@gduperrey Rolling update of my homelab through Xen Orchestra worked flawlessly. Thanks!

RE: A question for the creators of XO
@jasonnix As @DustinB already explained, Vates is the company behind XCP-ng and Xen Orchestra (XO). XCP-ng Center was (and still is) a community driven project not related to Vates. Search about the pro's and con's in the forum, there are a lot of good arguments. But for commercial customers, XOA is the way to go (and for most homelab user probably as well)
Last time I looked, XenCenter is now closed source and even behind a paywall (not sure about that), while Xen Orchestra is fully open source with all functionality in the from source version.
Since this is getting off-topic: did the communities feedback on your initial question help you to move forward? All good for your panel on Xen?

RE: A question for the creators of XO
@jasonnix said in A question for the creators of XO:
I want to make a panel for Xen
If by
make a panel for Xen
you mean a dashboard to visualize or controll a Xen-enabled host or the virtualized guests, I would suggest to start learning about XAPI or better XO API.How you design or implement such a panel is up to your ideas, capabilities and choice of the tools you are familiar with, be it Ruby, PHP, Java or Javascript. Also check out XCP-ng Center which is maintained by @michael-manley in a community effort and uses C# to controll Xen-enabled hosts.

RE: A question for the creators of XO
@jasonnix said in A question for the creators of XO:
I want to know what features are there in this project that PHP or Ruby can't do
A feature comparison (or retrospective evaluation of the decision) is not needed anymore for a project that already choose a development environment years ago, engaged people with the required skills and build a deployment process around a commercial product.
Could XO be build with PHP or Ruby? Probably yes. Does it add value to the product? Probably no, because it working just fine with Javascript as a future proofed development environment.
I apologize if I still not get why you are asking.

RE: A question for the creators of XO
@jasonnix On the other hand, why should one use Ruby or PHP when Javascript fits the projects requirements? Javascript is a State of the Art development environment with a lot of available and capable resources. According to the (maybe biased ) conclusion of the State of Javascript 2022 survey, JavaScript and TypeScript are more vibrant than ever. You don't normally change horses in projects like this without good reason.
Would love to understand why you are asking though.

RE: Custom email
@frank-s Probably not exactly your use case, but I use the Dragonfly Mail Agent (DMA) on Debian for sending mails in automation scripts or when working on the CLI. The mail plugin of XO from source handles the rest. As @pdonias said, it would be good to understand your requirements.

RE: 2 weeks break for me
@olivierlambert Take your time and relax . These have been and will be busy but also exciting times for Vates and the community too. Looking forward to have you back on the forum.

RE: Multiple XO applications for one pool?
@mestafin XOA/XO is an appliance with a web UI that should run as bare-metal or virtualized instance. It is a multi user management solution, that can handle different pools and user. Backup of a VM allows for easy restore. No need to install it on a notebook.

RE: Pool & Metadata backup - no option for email notification recipient
@mathieu You can add multiple recipients (email addresses) in the
backup-reports
plugin to which all pool and metadata backup reports will be sent. I use a shared mailbox here, so I have never had the requirement to specify more than one recipient. Thetransport-email
plugin is used to configurate the SMTP settings to send emails. For the sake of simplicity, I use the same shared mailbox here. -
RE: disable vswitch controller
@sb2014 Did you try
xe sdn-controller-forget uuid=<uuid of sdn-controller>
at the console from Unable to set XCP-ng VIFs to Locked? Not the same issue, but maybe a solution.Could you please format the output in your post as code (insert ``` before and after the output)? This really helps with readability.

RE: Used server suggestions
@drewq Your choice depends on what you want to play around with. To explore 10G, different physical network scenarios (like seperate management, VM/storage motion, VM traffic, VM backup or out of band management networks) or GPU passthrough, you can start with something like a 8th to 12th generation Dell SFF or MT with vPro.
I actually use four Dell 9010 with Intel i5-3550 CPU @ 3.30GHz CPUs and 32GB RAM in my playlab (three XCP-ng hosts, one TrueNAS host). These 3rd generation systems are already very old, but they are also very cheap on ebay and you can tinker a lot with virtualization. If you need more memory or expansion options, a workstation or server is the better choice. I personally like the Dell Poweredge R720 or R730 series.
My home production cluster lives on two HP ProDesk 600 G6 host with a 10th generation CPU, 64GB RAM and a 128GB SSD for XCP-ng and 2TB NVMe for local SR each. In everyday life, the single 1G network card is not a real drawback for me and I can use VLANs to create different networks. Unfortunatly, the HPs vPro only support SOL and not KVM and that is a real shame.
For general information on used server /r/homelab is also a good starting point. But be prepared for some "watch your power bill" or "space heater" comments though.
Edit: @Virtual recommended the MS-01 and you can find good and detailed reviews by Craft Computing or ServeTheHome on YT.
