Confirm commit 1a7b5 backups completed successfully.

Updated AMD Ryzen pool at home and update two Intel Dell r660 and r640 pools at work. No issues to report back.

@stormi

Thanks for the reply back. Update when sucessfull. Windows Server 2025 iso now properly installs.

At work I was not able to install default certs for UEFI due to one failing to download. Run these updates and I was able to successfully install the certs to the host.

@dinhngtu Well those directions didnt work as I was unable to locate the setup.exe file in any of the vmware directories. I asked google ai how to force uninstall the vmware tools and started to follow those directions of maunally deleting the services and folder and registry entries. However the vm pysically became unbootable. It would not show the logo of the bios starting up. The vm would appear to be starting up but no console screen would load. I even tried to restore from a backup taken two days ago. That VM started up and of coarse windows wanted todo updates and vm became unbootable again.

I deleted all previous vm and did a fresh migration. This time i did remove the tools prior to the migration. VM is back working.

@Pilow

Did dirty upgrade left all boxes checked and vm is setup to update drivers via windows update....

I have rebooted vm and restarts no issues.

@dinhngtu same mine where two fresh VMs fresh install of server 2025. Older iso works newer iso does not. For me the newer iso the system rebooted 2 maybe 3 times then crashed to a hard power off of the vm.

Again no xen tools installed as os never finished installing on a fresh vm. no OS upgrade.

Correction XCP-NG backups are Application aware... Just not accessible from the right click menu on the backup. If you click from the menu bar at top it is available...

@Pilow

I thought restarting tool stack affected both host? Either way did try that but on host 1 originally. So i restarted on host 2 (where problem is). still no locked. I rebooted host 2 and that seem to do the trick. Took a few min for garbage collection to complete. All clean now.

Thanks.

@Pilow didnt realize veeam support for xcp-ng entered public beta. Downloading now and going to start testing.

Not sure this as been mention before You create a tag called "Backup" and in your backup job you can have it backup every vm with that tag. Why is this not an option for Mirror jobs? I have some VMs i want to mirror to another Remote while others not so much.

Having tags would make this a lot easier to manage. So you dont have to re-edit the mirror job to add or remove a vm to be mirrored.

@dfrizon interesting i tried 24.04.2 iso and that failed but you state 24.04.1 worked?

Other thread believe this is a Ubuntu issue but as stated ISOs that have been download for some time worked in the past until recently.

Maybe related to my issues as well... https://xcp-ng.org/forum/topic/11476/error-installing-ubuntu-24.04-on-new-xcp-ng-host.?_=1761746474282

@Jeremyz1

Thank you for also confirming issue. I think Vates is aware from comment in support ticket but still waiting to hear back. I did some extensive testing last night with 7 host consiting of 3 pools.

the one time last night i was succuess i want sure if it was because i rebooted everything or because i changed from LVM group formant to traditional format during the install but was not able to replicate again.

doing some further testing ubuntu server 25.04 will install successfully. Server 24.04.3 lts will not. Desktop 24.0.2 will install successfully.

After multiple test on work server and home lab. I did managed to install ubuntu 24.04.3 by telling the installer to not format the drive in lvm group. But after trying to replicate that i was never successful.

This was tested with between 7 different host. 3 home lab and 4 at work. For at work have paid support. All host fully updated XOA - 5.111.1 XO-CE commit 87471 all host on 8.3 with no available updates.

I also test other Ubuntu templates all end with the same results.

Yeah not sure. Trying to remember when i was last successful in creating new vm with ubuntu 24.04.3. The best i can come up with is on 10/22/25 as i created a new vm within a day or two from that date.

But that fact that two separate systems showing the same problem....

@dinhngtu

Just tried Ubuntu 24.04.3 on my work servers and the install failed their as well I will open a support ticket as i have support on these servers.

Edit - Opened support ticket - Ticket#7746678

@dinhngtu

Could you tell me where and how to fetch error report?

The only other cavoite i can state but i dont think should have caused this, but just to be 100% transparent.

When i tried connecting the new host to xo-ce i did try to add the new (Intel) host to a pool that consited of AMD cpus. I also tried using the same SR for VM storage as the other pool but it would not add the SR to the new pool but only to the host.

I have since created a new SR for the vm storage but i was able to mount the ISO SR from the other pool to the new pool. That ISO SR can been see by both pools and see the contents of the SR.

As stated before i was able to success fully install Windows 11 and Ubuntu Server 25.10 with no issues. Only Ubuntu 24.xx.xx fail to install.

@manilx

success. Updated to Commit 45ef6

Ubuntu 24.04.2 installer failed as well...

Fresh download of 24.04.3 iso and same error. Also getting same error on my existing host also.

I at first i didnt try any other Linux distros as I primarily use Ubuntu. However i just tried 25.10 and that worked.

Will try again with 24.04.03 iso again or redownload the iso.... Had no problems with the iso before.

@olivierlambert

What more information is needed?

Fresh install of xcp-ng 8.3 on host. Join host to existing xo-ce as 2nd pool (single host).

Connected nfs SR for vms and connected same ISO SR from pool 1.

did secureboot-certs install on host.

Created new vm for windows 11 and installed successfully.

Create new vm for Ubuntu error doring install.
