Just to give an update.

Evening @pierrebrunet

My bad.

I am now on commit b440f and the issue persist.

I have written you a message with the link to the file.

Marc

Hi @pierrebrunet

With commit c74a8 the problem is still present but the transfer was completed again.

Unfortunately my installation does not recognize the "xen-bugtool" command. And both log files are not present.

Is this something that needs enabling after install of XCP-NG?

Unfortunately and unnoticed my syslog-server did not receive any messages from XCP-NG in the last 30 days.

Other inputs work

**Edit:

I have deleted and re-added the syslog-server with port and now logs are being send to Graylog.**

Thanks for your assistance y'all.

Regards,
Marc

With commit caa17 the transfer did not happen again and fails the with the known message.

Marc

Quick Update:

Was looking good with commit cf26d.

After the transfer completed the VDI of that particular VM was still in use, according to XO.

So still failure on the job.

Marc

Hi @pierrebrunet.

I have deleted the "parentless" VDIs and snapshots.

So the "Unhealthy VDI" page is empty for me.

So everytime I retry with the VM in question it is creating a new (full) backup-chain.

Marc

Problem still present in commit 04deb.

Here is the log from the XO6 interface:

I am giving a short "report", when there is new version out and I have tested it.

Nice weekend @y'all

Regards,
Marc

Problem still persists with commit e9b66.

Thanks for the support!

Regards,
Marc

Commit 1ba82 did change something. It transferred the VDI but then fails with the VDI_IN_USE on that particular machine.

Regards,
Marc

The problem still persists with commit e376a.

After installation of updates to XenOrchestra I reboot the VM. Still no backup on this one VM possible.

For now I have created a separate backup job which seems to be working.

Regards,
Marc

I have restarted XO as well as my NAS several times since Saturday.

Still no change.

Regards,
Marc

Hi @pierrebrunet.

Thanks for the tip.

Didn't help, unfortunately. Same error message regarding VDI_IN_USE.

Regards,
Marc

Hi @DustinB

The VM could be backed up successfully with the same warning about the "disk parent":

I am using "smart mode" for backup jobs. The standalone job went through with and without "smart mode".

Removing the tag from the VM in question and adding it again did not help. I have also deleted the snapshot linked to the backup job and retried, with no change in behavior.

The VM is shutdown and I only turn it on when I need to. During backup it is usually not running.

Thanks again.

Marc

Hi there.

Given is a community edition XO on commit 3500d.

Since June 6th one out of seven VMs is no longer backing up.

It is always the same VM which is failing.

The remote is working (six VMs back up without issue).

It seems XO has trouble cleaning up the backup directory:

Here is the full backup log:

Maybe this is linked to the thread by @andrew :

https://xcp-ng.org/forum/topic/12249/xo-error-warning-clean-vm-directory.-unhandled-error-while-checking-alias./37

I upgraded today to commit 3500d, rebooted the XO VM and retried the backup. Still failing.

Thanks for the assistance.

Hi @McHenry .

You should obfuscate the IP address in your first screenshot. Also check your profile and private chat

Hope everyone had a joyful Christmas and I wish everyone the best for 2026.

Hi.

I am a little late to the party.

I have currently a stable situation with a Netbox 4.4.3 installation and XCP-NG 8.3 (up-to-date).

Which exact commit for XenOrchestra fixed the issue for me personally I cannot tell. Now it is syncing just fine.

Regards
Marc

@olivierlambert said in Xen Orchestra commit a62ac Templates not loading data:

The fix was merged in master, you should have it now if you update to the latest commit

Very cool. Works perfectly fine again.

Love this

Keep up the excellent work you guys

Regards,
Marc

@olivierlambert

I installed via https://github.com/ronivay/XenOrchestraInstallerUpdater

@manilx said in Xen Orchestra commit a62ac Templates not loading data:

@olivierlambert Created issue on both githubs.

Awesome!

I found an older snapshot of XenOrchestra CE with commit 29af0, which is also "broken" in that respect.

Regards,
Marc

@manilx Thanks.

I was 24 commits "behind" before updating to the latest one. So I could not say, in which commit the breaking change was included.

Regards,
Marc
