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.

Reach out to who's script you are using for deploying XO from sources.

This script - https://github.com/ronivay/XenOrchestraInstallerUpdater there is an option in the config file to enable XOv6. There are concerns with not being fully ready to its disabled by default. I currently have not any issues related to that.

@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.

as @MBNext stated disabling Purge snapshot data when using CBT worked for me.

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.

@mguimond
Not sure how old your XO is but this is the current Commit. Master, commit 5349f. Suggest try updating and try again. Maybe someone from Vates will have more information.

@WorkAccount1000

Prior to myself finding that option in the config file use to run this command that worked as well..

cd /opt/xo/xo-web

sudo yarn run turbo run build --filter @xen-orchestra/web

@bvitnik thanks for that info. There is so much to learn with linux. Not that there is alot to learn with windows. I am still learning new stuff every day but still know just enough to get myself in trouble with Linux.

@Pilow I try the dhcp4 vs dhcp

So I started with a Ubuntu 24.4 image from XOA hub. I create a new vm from that image with my cloud config from above. I start the vm up. Once booted I shut it down and remove the Cloud config drive. leaving 1 single os drive. I boot the vm up and fully update the vm and install a few minor tweaks. Then shut the vm down. Networking is configure dhcp.

If convert this newly created vm to a template. Then create another vm from this template. Even though the VM is generating a new mac address when the vm boots its still getting / using the same ip from vm used to create the template.

If i put either network configs in during vm creation from new template i get no ip address. I cant log into console because the user does not have a password. I have tried to put password: userspassword in the config but that does not work.

network:
  version: 1
  config:
  - type: physical
    name: eth0
    subnets:
      - type: dhcp

or

network:
  version: 2
  ethernets:
    eno1:
      dhcp4: true

Think I figured it out. first i was using the wrong key. A lot of going back and forth trying new keys forgot to swap back to original...

new config...

#cloud-config
hostname: {name}
users:
  - name: newusername
    gecos: New User
    sudo: ALL=(ALL) NOPASSWD:ALL
    groups: users, admin
    shell: /bin/bash
    ssh_authorized_keys:
      - ssh-ed25519 AAAAC3....18ZbA

Any suggestions should I not use something in the above config if the server was in production?

So i am trying to learn how to use the Custom config / cloud-init for ubuntu.

If I add my ssh-key to my user account in Xen orchestra (XOA or XO-CE) I can select that during the vm creation and that works but the VM is stuck with the username ubuntu. I would to change that.

I am not sure if I am messing up the user creation or the ssh-key as i am not able to log in do to authentication error.

My config ---

#cloud-config
hostname: {name}
users:
  - newusername
ssh_authorized_keys:
      - ssh-rsa AAAAB3NzaC1.....XbZH6muQrfegKoTsuw== Generated By Termius

The above is not my actual key. In the key saved in user profile stops before the"==" and as stated that key works. So i assume if I correct the config to remove the "==" and after that key should work as well. So my assumption is the user name is the issue.

I would like to make the username to my desire but have the same permission as the user account ubuntu has when just inserting ssh-key.

Wait for vates to reply for more technical information. Take a look at this - https://xcp-ng.org/blog/2025/10/16/qcow2-beta-announcement/

you are at 1.5tb so I think you should be ok with out qcow2 support. I personal had some performance and other issues with it and disable as I didnt need 2tb support yet.
