Error installing Ubuntu 24.04 on new xcp-ng host.
-
Just setup a new Intel host and getting this error when install Ubunut 24.04. Windows 11 installed no issues.
I did have an rtx 4070 gpu passed through to the vm when it failed. I removed the gpu and the install still failed.

Hi,
We would need more details on your setup.
-
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.
-
And what about other Ubuntu version or Debian? Same issue?
-
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.
-
Ok keep us posted
-
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.

@acebmxer Could you fetch and send the error report somewhere?
-
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.

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

Smells a kernel bug in this specific version

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....

I can confirm this issue as well. Fresh vanilla install XCP-NG 8.3 on an HP server. Tried multiple builds of the Ubuntu 24 iso and multiple HP servers. All failed consistently. Installed patches on the host, rebooted and it worked. Went to install another VM today and having same issue again. I'm wondering if it was the patches or the reboot of the host that fixed it the last time. Worked fine with XenServer on same box, and I believe it worked fine every time with XCP-NG 8.2 on that same box. Its possible this just happens on XCP-NG 8.3

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.

@olivierlambert I passed through this a lot of times yesterday. Same scenario with Ubuntu 24.04-3. I tried to download the ISO a few times, tried to create the VM with templates, with "other install media", etc, and failed all the times. Strange that I sucessfully created a VM with the same ISOs a few days ago... To solve my problem, I had an older ISO (Ubuntu 24.04-1) where I installed sucessfully (apt update && apt upgrade after) and "stonks"!
-
@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.

@acebmxer Ubuntu 24.04.00 installed for me! I didn't run any updates during install. Perhaps didn't like something in the kernel that existed in 24.04.3. The 24.04 iso is available under ubuntu old releases.
