    @Bill.Oliver obvioulsy, licensing. If you are planning to put Microsoft VMs, beware of licensing with multisockets by hosts, you have to cover them all. By default, you should cover 16 cores with 1 Microsoft Windows Server Standard to get 2 VMs licensed. If you get two sockets, you have to double the licensing (and add 2 packs core to attain your cores coverage...) All licensing based on cores make you think twice when planning CPUs... If you want to, you can go DATACENTER edition, but you still have to cover all the cores...

    Did some more testing over the weekend and got some cleaner logs that are fully matched up. We ran the command 'journalctl -u xo-server -f -n 50' and see these to entries: Nov 15 14:26:10 xoa xo-server[552]: 2025-11-15T19:26:10.935Z xo:vmware-explorer:esxi INFO nbdkit logs of [WE-DS] WE-FS1/WE-FS1.vmdk are in /tmp/xo-serverGKTRzl Nov 15 14:26:10 xoa xo-server[552]: 2025-11-15T19:26:10.943Z xo:vmware-explorer:esxi INFO nbdkit logs of [WE-DS] WE-FS1/WE-FS1_1.vmdk are in /tmp/xo-serverCFf19t The log files were fairly large, wouldn't allow me to attach them, so i have provided them in a zip on dropbox if you want to take a look. From what I can pick out in the log files it appears that the transfer from VMware is complete or so it looks that way. After that I ran these two commands against the import tasks: xo-cli rest get tasks/0mi0ogg5f xo-cli rest get tasks/0mi0ogg5g The output for those is also attached. The one thing that stands out is in the "importing vms 17" is that WE-FS1.vmdk shows 'success' and WE-FS1_1.vmdk shows 'pending' Finally, I attached the logs from the host as well. I'm not seeing anything that jumps out at me as being wrong there either.

    @Joe_dev I have a MF unit with similar igpu. I was not able to get it working under any virtualization platform. There is something about amd igpu that makes passing it hard. I believe some have had it working under proxmox with custom kernel and video bios. I never bothered trying all that out so i just gave up on the unit.

    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.

    @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/

    This post specifically: https://xcp-ng.org/forum/post/57441 The person had issues to speak in English but wanted to tell this configuration worked. You can use the xen_wdt backend to rely on a Xen operation to force restart the VM. I have no idea how it works on Windows.

    @lawrencesystems I think this is quite common when you need to test certain scenarios with multiple hypervisors (backup, migrations, etc.). You only need a couple of HVs with a few tiny running VMs. We have done this setup with nested esxi many times for testing purposes. And since e.g. Ubuntu and Windows work this way, the problem is probably specific to Debian (and maybe others?).

    @infodavid Finally, I follow an existing topic and configure nut-server on the hypervisor to access the ups via usb. I know that Olivier is not fully aligned with the fact that the host is modified but IMO it is an acceptable change on my XCP-NG host.

    @lritinfra Something to consider also the HPE Intelligent Provisioning is the main way, outside of HPE iLO, HPE SUM or HPE SPP to update the server's hardware firmware. If you aren't using individual RPMs or SCEXE files for the task. With HPE Intelligent Provisioning and HPE SPP being able to update, both firmware and BIOS. As not all of the updates for firmware will be in a compatible format, for use with HPE iLO. I'm not sure if it has changed but an Administrator Password set on the BIOS (at minimum), also locks out (disables) access to the Erase option on the HPE Intelligent Provisioning. At least it does on my only HPE Server running an up to date BIOS, HPE iLO and HPE Intelligent Provisioning. Thus disabled HPE Intelligent Provisioning doesn't help with being up to date enough to fix vulnerabilities and bugs at hardware or firmware level.
