    @acebmxer I did install the certs, and everything went fine with that. But I never went back to try and install any uefi VMs through XO-Lite. Something I may or may not get back to, should really wipe the system and start fresh again to see how things have advanced. Things may be changing, and my lab may not have a physical place in my world. Which troubles me because I'll need to model things if this path turns into reality. Lots of unknowns right now.

    @cichy You can absolutely install netdata on your hosts https://xcp-ng.org/forum/topic/2288/netdata-package-is-now-available-in-xcp-ng, you simply don't get a SPOG from within XO unless you're on XOA. It certainly appears that netbox can be configured as well on XOCE [image: 1755097806418-d852a159-95cd-45c3-bab1-6656c15c9c55-image.png] This install is using my script, I can't speak for ronivoy's but the plugin is definitely there.

    @olivierlambert I Hello! I apologize for the long silence. Major medical and system hardware problems came up and had to be dealt with. I now have what I consider to be a very stable v8.3 install. I can report that the base i40 driver does not work with Intel x710 v9.54 firmware. In pfSense's console, both interfaces are report as active but there is no traffic flow, no response to a ping request, and the GUI is unavailable. I installed the alternate drive with both interfaces reported as active but again there is no traffic on the WAN interface. The LAN interface is ping-able and the GUI available. At this point I feel my option is to build the driver from source. As I am not a developer I asked (don't laugh) ChatGPT for a recipe. The installed kernel is 4.19.0+1 and ChatGPT claims 4.19.19-8.0.38.2.xcpng8.3 is the development kernel and is installed. Your input would be greatly appreciated. Best regard

    As @Andrew said, your host itself is unhealthy, you might be able to disassemble the CPU and heatseat, clean it up and add some new paste to address the issue with the CPU overheating (if the paste is shot). As for the memory issue, run a memtest on the host and see what is reported.

    CPU speed is great to enhance all Xen operations (using grants for example). But tapdisk got a lot of room to be better outside that, thanks to multiqueue and so on. However, it's not clear if it's better to improve tapdisk or making something different. This is an active topic of reasearch.

    @acebmxer said in Windows Server not listening to radius port after vmware migration: After migrating our windows server that host our Duo Proxy manager having an issue. [info] Testing section 'radius_client' with configuration: [info] {'host': '192.168.20.16', 'pass_through_all': 'true', 'secret': '*****'} [error] Host 192.168.20.16 is not listening for RADIUS traffic on port 1812 [debug] Exception: [WinError 10054] An existing connection was forcibly closed by the remote host After the migration I did have to reset the IP address and I did install the Xen tools via windows update. Any suggestions? I am thinking I may have the same issue if i spin up the old vm as the vmware tools were removed which i think effected that nic as well.... On your VM that runs the Duo Auth Proxy service, check if the service is actually listening on the external IP or if its just listening on 127.0.0.1 If its just listening on 127.0.0.1 you can try to repair the Duo Auth Proxy service, take a snapshot before doing so. Also, if you're using encrypted passwords in your Duo Auth Proxy configuration you probably need to re-encrypt them, just a heads up, since I just had to do so after migrating one of ours. Edit: Do you have the "interface" option specified in your Duo Auth Proxy configuration?

    What to do about Realtek RTL8125 RTL8126 RTL8127 drivers

    @stormi Unless new Dom0 is Kernel 6.15 or newer (with updates), this will be an ongoing problem to support the newest hardware as they seem to keep updating the chips (you can't stop progress). The current r8125 driver in 8.2/8.3 supports the 8125 and some 8126 chips, but not 8127. Other than supporting the new hardware versions of the chips, I have not seen any real complaints posted about the current r8125 driver (may be there are some Vates tickets?) While the risk on the new driver is low, it is different (not just an update). I agree that it would be best to have r8125-module-alt for the new code and then r8126-module and r8127-module. Note, that the new r8126-module driver should not be installed without the r8125-module-alt as the existing r8125-module would conflict with the new r8126-module driver. The work is already done (compiled and running)... I'm just waiting for Realtek to fix some issues with the new code before it's worth fully testing the drivers (issues already acknowledged by Realtek).

    We have some sites with a single-host XCP-ng pool backed by a small UPS. We install nut directly in dom-0. I'm aware of the policy for adding anything to dom-0 but we believe this usecase fits in the recommendations (simple enough, no vast dependencies, marginal resources usage, no interference ...). With proper testing works pretty well. nut inside a dedicated RPi definitely makes sense for a site with multiple hosts backed by the same UPS.

    Hello, We tried the compression feature. You "can see" a benefit only if you have a shared storage. ( and again, the migration between 2 nodes is already very fast, we don't see major difference, but maybe a VM will a lot of ram ( >32GB ) can see a difference. If you don't have a shared storage ( like XOSTOR, NFS, ISCSI ), then you will not see any difference because there is a limitation of 30MB/s-40MB/s ( see here: https://xcp-ng.org/forum/topic/9389/backup-migration-performance ) Best regards,

    Migrating from XCP-ng Windows guest tools to Citrix

    I did it that way so as to get the old Citrix driver first, and then let it update and watch it reboot. That was my logic anyway. @dinhngtu said in Migrating from XCP-ng Windows guest tools to Citrix: @bberndt Okay, I managed to reproduce your situation. I think it's because the "driver via Windows Update" option was enabled after installing the XS drivers, which caused the drivers to lock onto the non-C000 device and prevent updates from coming in. Normally, XenClean should be able to fix the situation. But if you want to fix things manually, or if things still don't work (C000 is still not active), here's a procedure that should fix the problem: Take a snapshot/backup/etc. Keep a note of static IP addresses (if you have any; there's a chance those will be lost). You can also use our script here: https://github.com/xcp-ng/win-pv-drivers/blob/xcp-ng-9.1/XenDriverUtils/Copy-XenVifSettings.ps1 Reboot in safe mode and disable the non-C000 device. Reboot back to normal mode; it'll ask you to reboot a few more times. The C000 device should now be active and you should be able to get driver updates again. (Optional) You can now enable and manually update the non-C000 device (Browse my computer - Let me pick).

    Do you have any SR using a VM? (like an ISO SR in a NFS share inside a VM). This is freezing NFS and makes host taking half an hour to restart. Logs should tell you why the RPU failed if it failed

    It's impossible to answer right off the bat without knowing more in details what's going on. HA is a complex beast, and combined with HCI, requires a lot of knowledge to find what's causing your issue, between both xha and XOSTOR. In other words, it is very demanding to analyze all the logs and trying to make sense of it. However, I can give you some clues to make sense of it: The HA log is at /var/log/xha.log. When you shutdown a host, you should be able to watch (on each host) what the HA is deciding to do. My gut feeling: there's maybe a XOSTOR issue making the heartbeat SR being unavailable, and so all hosts will autofence Then you need to understand the XOSTOR logs for why the cluster wasn't doing what's expected. My best advice: remove HA first, and only then investigate on XOSTOR. Kill on node (not the master) and check if your VMs are still able to start/snapshot/write inside.

    PXE Boot from new VM not working

    @JBlessing as it looks like it does start, it looks like the networking side is working, at least at first. Just for debugging purpose you could try to switch that VM to BIOS instead of UEFI if it is possible, maybe it is related to what the pxe is starting in the VM. You could also try switching the VM between realtek and e1000 NIC, at this stage, PV drivers are not there so it is using an emulated NIC, maybe the image your PXE starts doesn't like the one you're using and it gets stuck somehow. As you're already using it with vmware, I assume you know how to size your VM, but if you went for a tight RAM value for this VM, you could try to give it more RAM to see if that could be related, as everything has to fit in RAM at some point, we may be using more at startup than vmware… Hope one of this can help

    About the xsconsole: sometimes it's not refreshing. You can try to get access to the console, then type "xsconsole" it will start it and you should see it works You must have the master up to date if you want your slave to connect again. I never tried to elect a new master in the middle of the upgrade, I would discourage it. Better shutdown some VMs on the master, upgrade it and you are automatically back on track.
