    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).

    @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.

    Using dynamic memory is known to be prone to causing occasional issues. Thanks for the feedback. Oh, by the way, regarding vTPM and snapshots, we finally established that it's fully supported by XenServer 8 and that the documentation was just out of date.

    Right, so yeah I did just that - disabled HA and have been keeping an eye on the logs as well as general performance in the env. Glad to know my actions align with your recommendations at least There are a couple of hosts that get a lot of these sorts of messages in the kern.log: Apr 25 08:15:33 oryx kernel: [276757.645457] vif vif-21-3 vif21.3: Guest Rx ready Apr 25 08:15:54 oryx kernel: [276778.735509] vif vif-22-3 vif22.3: Guest Rx stalled Apr 25 08:15:54 oryx kernel: [276778.735522] vif vif-21-3 vif21.3: Guest Rx stalled Apr 25 08:16:04 oryx kernel: [276788.780828] vif vif-21-3 vif21.3: Guest Rx ready Apr 25 08:16:04 oryx kernel: [276788.780836] vif vif-22-3 vif22.3: Guest Rx ready Am I wrong to attribute this to issues within specific VMs (i.e. not a hv performance issue)? I know one of the VMs that causes these is a very old centos 5 testing VM one of my devs use and the messages stop when it's powered down. Is there any way to easily associate those vifs with the actual VMs they are attached to? My google-foo failed me for that. Other than that, I noticed my nic firmware is a bit old on the X710-da2's I use so I'm going through and upgrading those with no noticeable changes. I'm fairly hesitant to re-enable HA without tracking down the root cause.

    @DwightHat said in Stuck in maintenance mode after joining pool.: When I try to look at the host in Xen Orchestra it just says "An error has occurred". Check to browser's Dev Tools console when this happens. It will likely contain some additional details. You likely need to check the logs to find out why you are encountering this issue. Many times the "stuck in maintenance mode" issue is related to an unmountable storage repository. https://docs.xcp-ng.org/troubleshooting/log-files/
