@olivierlambert okay, understood. it is small minor cosmetic problem as of now. need to get you an access to our internal developped app, to show you the potential of sub-xoas ^^' almost out of alpha phase

Hi, There's thousands of different S3 providers in the world, and sometimes, some of them are behaving weirdly. We do test our S3 capabilities with the most popular S3 AWS SDK (in Node), so it's very likely that the issue comes fro the provider itself. However, we have no information in your post about which provider you are using, so it's hard to tell.

Hi! See https://docs.xcp-ng.org/releases/release-8-3/#4k-native-disks and https://docs.xcp-ng.org/storage/#largeblock-sr Note that qcow2 format is supporting 4k natively, and it's in release candidate stage, maybe the right approach in a near future

REST API VBD order thing: quetion for @mathieuRA

What is the purpose of this discussion? You did create this thread, I think you would know what's the purpose of this discussion Have you asked VEEAM for a solution, because it seems more VEEAM-related question after all I have no idea what it means regarding "replication is not possible for this Oracle point via VEEAM". Remember we aren't from VEEAM in here, so you should explain more precisely what do you expect from us to do despite it seems to be a VEEAM limitation?

Something to document @thomas-dkmt

Hi, You mean persistence after XCP-ng updates, right?

@TeddyAstie I have to get my hands on a null modem cable first. Will try get that next week and then test. Will get back when I have some results. I have never tried that before, just to be sure: Idea is to connect serial port of the xcp-ng server < null modem cable > serial port of another PC, right? And then just i.e. putty on the other machine and the xcp-ng server should send out console text via serial.

At the spots in the graph where my XO CE instance used around 2GB of RAM it was freshly restarted. Between 31.01. and 03.02. you can see the RAM usage climbing and climbing until my backup jobs went into "interrupted" status on 03.02. due to Node JS heap issue as described in my error report in post https://xcp-ng.org/forum/post/102160.

@randyrue on our side, we do not use custom fields, but TAGs. working well. depends on the number of custom fields you manage, and perhaps not usable because you need field:value ? but nested tags could do the trick : field=value [image: 1770190720889-99027821-448b-415e-ba89-321260247f73-image.png]

@dinhngtu said in XCP-ng Windows PV tools announcements: Hello all, The XCP-ng Standard VGA Display Driver for Windows v0.1.29.2216 has been released https://github.com/xcp-ng/win-xstdvga This driver provides high-resolution consoles and resolution switching for Windows VMs running on the XCP-ng hypervisor. This is a beta release. This driver will eventually be integrated into the main Windows PV tools package. Driver pulled for bug fixes. Will come back soon Test on windows 11 vm no issues to report.

Hi! ISO-SR over HBA/FC would be very nice, especially when migration form a SAN vmware-System to XCP-NG. One other thing is altering. Errors like "VM cannot be migrated" or similar should not be silent but should be very visible / even mailed to the admin. Another thing (could be cosmetical though) in my opinion is that a failed Rolling upgrade remains visible with a half fulled progress bar in the task-view. this is confusing.

@Danp thank you for the help. I have looked at all vhd in my disk and they are all good as per vhd-tool check. Regarding the logs in xensource logs the first error is showing up few mins after I trigger the export. #!/bin/bash # Script to check all VHD files in the current directory using vhd-tool set +e # Don't exit on error total=0 failed=0 echo "Checking VHD files..." echo "" # Loop through all .vhd files in current directory for vhd_file in *.vhd; do # Skip if no .vhd files found [ -e "$vhd_file" ] || continue ((total++)) # Run vhd-tool check if vhd-tool check "$vhd_file" > /dev/null 2>&1; then echo "PASS: $vhd_file" else echo "FAIL: $vhd_file" ((failed++)) fi done # Report echo "" echo "====================" echo "Total: $total" echo "Failed: $failed" echo "====================" [ $failed -eq 0 ] && exit 0 || exit 1 /checkvhd.sh Checking VHD files...

Hello Hope this help here is how I manage to configure GPU Passthrough. In my case I have follow the documentation on XCP-ng website : https://docs.xcp-ng.org/compute/ To sum up with XOA 8.3 here is what I did: ssh to XCP host, to identify the GPU PCI and run lspci to find my GPU. [root@xen ~]# lspci ... 0f:00.0 VGA compatible controller: NVIDIA Corporation GA102 [GeForce RTX 3090] (rev a1) Then disable the GPU for being used by XCP-ng itself( Dom0) using the XCP-ng uuid [root@xen ~]# xe pci-list uuid ( RO) : 7970825f-dd1c-c270-93a3-6761f00e1362 vendor-name ( RO): NVIDIA Corporation device-name ( RO): GA102 [GeForce RTX 3090] pci-id ( RO): 0000:0f:00.0 xe pci-disable-dom0-access uuid=<pci uuid> 3 reboot the XCP-ng host 4 Then from XOA attached the PCI related to my GPU to my guest VM.

PS: I have an issue, I don't have output to the Display port or HDMI of this video card, which is not a blocker for me as that's not my immediate needs. Best.

Mentioning also @Team-Hypervisor-Kernel who now manages the drivers. Maybe it's related to https://github.com/xcp-ng-rpms/microsemi-aacraid/issues/2#issuecomment-3837183087 It looks like the switch to the vendor driver instead of the kernel built-in for 8.3 (initiated by XenServer, and that we followed at the time as it was probably made in order to support newer cards) was not without drawbacks. 0nelight created this issue in xcp-ng-rpms/microsemi-aacraid open Microsemi Adaptec Series-8 Card not working in XCP-NG 8.3 #2

@henri9813 Ahh alright, I understand now! Thanks for clarifying.

I just want to add that I am seeing the same issue with Ubuntu 24.04.3. Creating a VM does work, but it crashes immediately when trying to start it for setup. I have not yet tried the approach of starting with 24.04(.00) and then upgrading to the lastest version due to lack of time. We are still using XCP-NG 8.2.1 on the server in question. If an upgrade to 8.3 solves the issue, please let us know. Reading the thread, it appears to have the same problem, though. Processor is an AMD Ryzen 9 3900X. We have not had any other issues with the system and it's been running for a few years.

@dinhngtu I think it just have been a bad migration or the Win 11 Template did other things to the windows 10 os. Since new test vm did not show the time issues, and a fresh migration of the vim with correct template selected did not have the issues either. I dont know but maybe there is a way to put detect the correct VM template or make note. I didnt think using the win 11 template would have caused issues since using the "wrong" template on vm creation does not have the same effect.
