If you proxy (or reverse proxy) any stuff, yes, you need to have a fixed address for the proxy.

@Andrew Yes, that offscreen was the problem..... Perhaps place it more to the left.

@manilx Nice was about to ask this too lol. Glad someone point this out already

@olivierlambert - Working now! Thanks!

Yes, that's the issue, the max vCPU in Advanced tab. It's probably at 42 while you only have 32 physical CPUs. Therefore, the VM won't boot. See an example screenshot: [image: 1726217639918-8728f260-893b-4601-b8b2-43b39b9d6806-image.png]

Hi, We offer air gap services to get you pre-bound XOA without the need for any Internet connection Otherwise, the workflow you used works too (configure XOA with a connected env and then export it). See https://xen-orchestra.com/docs/airgap.html for more details. Also, you can use our airgap deploy script in here: https://xen-orchestra.com/blog/xen-orchestra-5-95/#️-air-gap-features

ok thank you!

ah ok, thanks for the information.

@rongage I don't know if anyone else has it working correctly on CentOS Stream 9. I know that it works on recent versions of Debian and Ubuntu, so why not try one of those?

With classical export (ie VHD and without NBD) you cannot "resume" a backup. Now it's possible (technically with NBD) but it's not done (yet). But we improved a lot the retry vs the original backups in VHD.

I don't "need" to deploy with xo-lite I just wanted to report it in case it was a bug with static ip configuration.

In theory, like thinking on top of my head, an agent in the physical machine that will be able to replicate the VM files in the same format than the XO backup, with also the "machine metadata" (CPU, RAM etc.). Then, if something goes wrong, you could restore a backup as a VM from the real machine.

@olivierlambert thanks for the quick reply Olivier, We have cloudinit working for Linux as that is working like a charm, hopefully a MS cloudinit god will reply and will be able to help me out

@Andrew it was related to a switch configuration mistake, thanks anyways.

Yes, you can ignore static min, 99% of the time it's not relevant.

My apologies @Danp , I had misunderstood the comments on the other commands in that KB article. Good news, things are working, but it didn't seem like they would be. xoa run npm i -g --unsafe-perm https://xen-orchestra.com/xoa-updater.tgz Seemed to work. I was then able to run systemctl restart xoa-updater and xoa-updater --upgrade.

@billcouper I 100% agree with you. I will add to this that it would be amazing if RX and TX nic/SFP errors could be made visible in the interface as well. reason why i mention this is we recently had a problem on one of our hosts storage links where due to a dirty fiber we had some problems (vm's going to read only, crashes, very poor IO). Due to how dom0 sits as a VM we could not get stats off a nic using ethtool or snmp. It took WAY to much trouble shooting to figure out that our issues was caused by a dirty fiber on the servers side. the more native/local self monitoring/alerting xcp-ng and XOA can do, the better.

I do run XOA on its own dedicated host/dedicated pool, so the xcp-ng cpu scheduler does not cause issues with other busy production VM's while backup tasks are happening. this also allows XOA to use 100% of cpu cores making backups (especially with compression on) faster. xoa does DR back up to the primary pool in case something happens to the host its running on.

Yes, you can always export/import the config on a working install. So it's a problem on your build, it's really hard to tell where's the culprit (because you built it, you see why we distribute it via XOA for production/professional usage )
