    Updates are live now Thank you everyone for your tests and your feedback! This includes updates that you have tested, as well as security updates that were under embargo. Check out the blog post for the full list of fixes and any post-update steps: https://xcp-ng.org/blog/2026/11/10/november-2026-security-updates-3-for-xcp-ng-8-3-lts/ If you installed the kernel from our last call for testing, please read on. You can check with rpm -q kernel. The released kernel is not the 4.19.19-8.0.49.3 you tested, but 4.19.19-8.0.46.16. Its release number is lower, so a regular update will leave your hosts on 4.19.19-8.0.49.3. We identified some issues in 4.19.19-8.0.49.3. To downgrade and install kernel-4.19.19-8.0.46.16, run the following commands: yum clean metadata yum downgrade --setopt=protected_packages= kernel-4.19.19-8.0.46.16.xcpng8.3 yum update reboot The usual update rules apply: pool coordinator first, etc. We expect to release a new kernel in a few days, and it will install as a normal update from either version.

    Hello, The hang bug will be fixed in a future release of Xen, but Windows requires enabling all Viridian extensions (currently 6) to ensure optimal performance and reliability. Enabling Viridian extensions also fixes the hang bug via a different way. On Windows guests, please reenable all Viridian extensions using these instructions: https://docs.xcp-ng.org/vms/#enabling-viridian-extensions

    right, we are moving all Backup pages in Administration tab (https://xen-orchestra.com/blog/xen-orchestra-6-10/), but we probably forgot to say we removed this "Backups" tab from the Site view...! Create/restore backup is in progress...!

    @dthenot For anyone stuck, here is what I ended up doing: I've manually hardcoded the controller_uri in /opt/xensource/sm/linstorvolumemanager.py on the new host, restarted the toolstack using xe-toolstack-restart and ran the xe host-call-plugin host-uuid=NEW_HOST_UUID plugin=linstor-manager fn=addHost args:groupName=linstor_group/thin_device command. def _get_controller_uri() -> str: # TODO: Check that an IP address from the current pool is returned. #addresses = _get_controller_addresses() return "linstor://10.25.254.100" #return "linstor://" + addresses[0] if addresses else "" After that, you should see the addHost command return True. It should be safe to revert the change to the _get_controller_uri() function and restart to make sure everything starts properly.

    @jqueiroz said: Bom dia a todos, Estou com um problema em uma VM, ela está ligando/desligando sozinha, repetidamente. Não encontro nenhuma mensagem de erro explicando o motivo. Alguém pode me dar alguma dica sobre como solucionar isso? Uso o XCP-NG 8.0 em um cluster de dois servidores HP Proliant DL-360, com o HA-Lizard. Tudo vinha funcionando bem até alguns dias atrás, quando houve uma queda de energia no datacenter da localidade. Tenho o mesmo arranjo de VMs/servidores em mais seis localidades, nenhuma apresenta esse problema. Analisar esse comportamento instável do cluster é quase como prever resultados complexos, parecendo a análise de riscos que a malta faz ao dar palpites no https://mostbetbrasil.lat. Grato. Como o problema começou depois da queda de energia e só acontece nessa localidade, eu começaria verificando os logs do XCP-ng e do HA-Lizard para entender quem está disparando os reinícios. Pode ser alguma política de HA tentando recuperar a VM repetidamente, algum problema de armazenamento ou até inconsistência no estado do host após a interrupção. Também vale conferir o estado do pool e os logs do Xen Orchestra, se estiver usando. Se possível, desative temporariamente a automação de recuperação dessa VM, com cuidado para não comprometer a disponibilidade, e veja se ela continua reiniciando sozinha. Isso ajuda a isolar a causa.
