    Hi, I can't tell it's the cause, but you should first use an officially supported client to manage it.

    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).

    I'm seeing something similar, not sure if its the same issue, but mine stops at 95% and just hangs there: [12:18 sto-xcp1 ~]# xe task-list uuid ( RO) : c1056d36-b195-056a-4121-e82d7fc851fb name-label ( RO): [XO] Importing content into VDI [ESXI]DEBIAN 12 fiona.iextreme.org-flat.vmdk on SR Local storage name-description ( RO): status ( RO): pending progress ( RO): 0.950 The nbdkit debug-log can be found here: https://mirror2.iextreme.org/temp/stderr Edit: some additional info Xen Orchestra, commit 1640a Master, commit 1640a

    @dinhngtu Thanks. We plan to migrate all Windows VMs from the Citrix tools down the road and only have a handful of VMs running these so far so will maybe hold off until the next version. Have been running the Linux rust tools for over a year with zero issues..

    log_fs_usage / /var/log directory on pool master filling up constantly

    Another thing that I noticed: despite enabling remote syslog (to graylog) for all XCP-ng hosts in the pool /var/log gets filled up to 100%. Adding remote syslog seem to not change usage of /var/log at all. Official XCP-ng documentation states otherwise here: https://docs.xcp-ng.org/installation/install-xcp-ng/#installation-on-usb-drives The linked part of the documentation indicates that configuring remote syslog can be a possible solution for /var/log space constraints which seems to be not the case. I feel like logging could use some investigation by Vates in general.

    Hi Forza, Have you finished migrating the workloads? If you are still looking for an easy migration solution, you can try Vinchin Backup & Recovery. It will replace the driver during migration intelligently.

    @olivierlambert Thank you for the reply. There was a thread on here about the iso not being mounted properly and I commented about having power off the vm and back and it will load the iso. This is specifically true with the 0.4.0 for linux. Image pulled from the XO Hub will not mount the ios if the vm is powered on. There is Yellow Explanation mark next to it. Power off vm and power on vm iso is ok. Reboot vm does not let the ios to work.

    @AtaxyaNetwork @Pilow @bvitnik Ok, knowing that the p2 partition was likely an old backup was exactly the breadcrumb that I needed. I confirmed via chroot and xsconsole that p2 was xcp-ng v8.2.1, and that p1 was v8.3. Then I was able to check the initrd files there. Namely I needed to see the updated dates and the kernel version. Thankfully, I saw initrd files on the backup that were the correct kernel and hadn't been disturbed. I then just cloned the initrd files from the backup partition to the p1 partition and BOOM. We booted right up. Much appreciated for the assistance, everyone. I'll still need to figure out why my disks are disconnecting, but that will be another post for another day.

    @Pilow Yes, we monitor observability metrics for guest OSes via other means but being able to see this info via the Xen Orchestra web UI along with the other metrics in the Stats tab definitely has is benefits, especially when performing initial troublehshooting or when dealing with groups in our org that only have access to the XO interface and not the other metrics dashboards. Don't get me wrong, I definitely appreciate all of the work that you are all doing to get these tools working and can't wait to start using them in production. I just need to make sure that they work as expected.

    @zpvS9 said in Error installing windows PV drivers 9.0.9137: I have this error too installing the new PV driver, after uninstalling Citrix driver, reboot, execute XenClean, reboot again, it said that an unsupported device is still present. I must uninstall the device by showing hidden device in Device manager and the Windows PV driver now install. So adding this step in XenClean would be appreciated. encountered the same problem with hidden base system that i needed manually uninstall to get the tools to work.

    @rustylh We really need more information to even begin. What version of XCP-ng are you using? What hardware are you using to run XCP-ng? What is the underlying storage where the VM resides on? What OS is the VM running? How are you taking snapshots, XO? How old was the snapshot? Were the guest utilities installed into the VM? You do know snapshots are not backups, right?

    So first, it's not an XO issue, which helps to diagnose it. Then, it might be a subtle XCP-ng bug indeed.

    said in Unable to enable High Availability - INTERNAL_ERROR(Not_found): said in Unable to enable High Availability - INTERNAL_ERROR(Not_found): @psafont Would designating a new pool master do the same thing? I ran the above command and its had no effect Well, I tried changing the pool master and when VMHost11 was the master I was able to enable HA. Switching back to VMHost13 as the master now so will see how that goes Everything is working as expected/hoped. So for anyone reading through this and wants a TL;DR Issue was related to the pool master setting, changing the pool master to a different host and then back to the original fixed the incorrect settings allowing HA to be enabled

    @lastcmaster Hi, it's a known issue that guest agent versions are not reported after migration or suspend. Other functionalities (poweroff/reboot, suspend, network change etc.) should continue to work normally.

    @flakpyro said in VM start stuck on "Guest has not initialized the display (yet).": @dinhngtu said in VM start stuck on "Guest has not initialized the display (yet).": You must run secureboot-certs clear if you're updating from 1.2.0-2.4 or 1.2.0-3.1 and have previously run secureboot-certs install with the above versions installed. Should we run this before installing the update or after 1.2.0-3.2 has been installed? You should run that preferably after updating all hosts. @lukasz_s said in VM start stuck on "Guest has not initialized the display (yet).": @dinhngtu thanks for advice i've upgraded varstored and varstored-tools: rpm -qa | grep varstored varstored-1.2.0-3.2 varstored-tools-1.2.0-3.2 than i've cleared varstore with secureboot-certs clear should taht folder contain more files ? ls /usr/share/varstored/ KEK.uth PK.auth db.auth what about dbx file ? That file is not shipped with varstored nor needed for now. We're validating the final 1.2.0-3.2 and preparing our guidance for the official update.

    What to do about Realtek RTL8125 RTL8126 RTL8127 drivers

    I have updated the drivers for the Realtek RTL812x 2.5/5/10G cards. So far they are working correctly. There are a few minor issues that Realtek needs to fix (for the next version, they say). Also the new Realtek firmware has not been added to XCP (but it's not required). The standard included 8125 driver for XCP 8.3 is not updated. To use the new driver install the new alt version of the 8125 driver. To support the 8126 install the required 8125 alt version first and then the new 8126 driver. The 8127 driver is also available for the new 10GB chips (I just got a production PCIe card for testing). The first issue I see with this card is, it is only a PCIe x1 card, so for full performance you need PCIe 4.0... There are other 8127 chips that support x2 so they will better support PCIe 3.0. Realtek will keep releasing new versions of the chips that will require updates to the drivers to function correctly. Even current versions of Linux needs updates to support the newer chips.

    @rk9268vc said in Having issues installing StartOS as a VM. Cant detect a disk for it to install to.: @TeddyAstie so can i just not run this OS on xcp-ng? is there no workaround? Would this run on proxmox? you can try adding to Linux command-line (in grub) xen_emul_unplug=never to disable PV drivers, thus making udev see ATA/NVMe drivers, maybe that's enough as long it's only the installer

    @Greg_E Do you mean autoupdate? It's not planned just yet, but you can update them with Group Policy using our guide here: https://docs.xcp-ng.org/guides/winpv-update/ (I think you don't need the Autoreboot setting any more, but it's worth testing). You can also use other tools like SCCM, PDQ etc. The drivers themselves are production-ready, and should not cause the domain controller issue on Server 2025. As for getting the drivers signed, the certificate did cost some time and money, but the most difficult part is dealing with Microsoft (since we're signing drivers, we needed not just a certificate but also a Microsoft hardware vendor account).
