    It's not meant to be used like that. If you are behind a NAT, the right approach is to have your XOA behind the NAT and inside the same network than the hosts. That's because hosts will always use and return their internal IPs to connect to some resources (stats, consoles etc.). XOA deals with that easily as being the "main control point" for all hosts behind your NAT (or a XO proxy if you prefer).

    @dinhngtu That's great, thank you. I think I'll wait a bit before switching tools. Everything's working perfectly at the moment. If you need me to test anything, just let me know. I'd be happy to test it when I have time.

    @olivierlambert Thanks! Very little time/ learning progress had been made/spent on this VM so I have gone ahead and created a new VM. The VM with the mysterious device still exists. So it would be interesting to know how but not essential.

    I had the same question but the responses here was amazing and the following blogpost nailed it. I hope it helps someone else too: https://techdirectarchive.com/2026/01/25/a-z-of-xcp-ng-and-xen-orchestra-setup-and-vm-creation/

    @Danp Okay, you're a genius, I upgrade this morning after my backup. So that could explain my issue. the mentioned thread is exactly my issue, but I didn't find it when I was searching about my issue. Thanks for all !

    No, from the XCP-ng point of view, the VM is still running without any interruption.

    @aghering You could try compiling it yourself on 8.1... I don't have an 8.1 test/build system.

    @NerdsOrder66 Ah, good question... My most recent environment included a Windows Server with 100+ RDP users. There wasn't anything special for optimization there aside from giving it a bunch of RAM/CPU resources, but YMMV.

    @olivierlambert No, the only thing I get with xl dmesg on the host, for some time back, are random brief reports of individual CPUs running above temperature threshold and then being clocked down, and then resolving. Nothing else.

    Indeed, but it's a bit old, and I would say for many reasons HVM with PV drivers is still the way to go for classical server virtualization mode

    Interpreting vulnerability scanners is a hard task. They are often screaming for "common cases", but remember XCP-ng is an appliance, so there are many cases where things do not apply. Happy to help you further via our pro support to answer in details your concerns

    @Danp So, that's the "best" way? Backup the meta-data with XOA, rebuild the OS drive - add the "new" server into XOA and restore the meta-data back to the new install? (I'm not doubting it is, just wanting to be sure we're understanding each other fully.) Seems straight-forward - but there's a ton of things I've done over the years that "seemed" pretty straight-forward that turned out to be anything but, and at least occasionally found I had no way back.

    @mmancina Hi you can try to call xe pif-scan host-uuid=<uuid of your host> , the NIC should appear after that.

    @bleader No, the opnsense box itself doesn't have wireguard (or anything else VPN-ish) running on it. It's mostly just a NAT with the normal variety of DHCP, DNS, ... services running on it.
