    If XO from sources, double check you are fully up to date in the first place. You maybe used an outdated V2V code that wasn't asking for the template, causing the issue you experience now.

    Hi, Have you tried the official documentation? Like in here: https://docs.xcp-ng.org/category/development-process/ edit: also, we already have an ISO loosely based on Alma 10, so maybe if you want to assist, that would be more interesting to sync with our teams

    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?

    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,

    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.

    @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.

    @Danp yes I ran "yum update" to be sure but "nothing to upgrade" on the pool-master. I try with storage (iscsi) NIC configured and without Storage NIC configured but the pool join freeze. Seems that persist some "SESSION" (may be referred to the slave host previously configured?) or some incoerence in the pool database... from /var/log/xensource of the slave host when try to join the pool: "session_check D:520c5b4e5b36 failed with exception Server_error(SESSION_INVALID, "

    @olivierlambert Agreed. The Citrix forum used to be very active, but especially since Citrix was taken over, https://community.citrix.com has had way less activity, sadly. It's still gratifying that a lot of the functionality still is common to both platforms, although as XCP-ng evolves, there will be continually less commonality.
