    @uberiain at this point, when I am uninstall the old XCP-ng center software, and install the new msi, I just realized the xcp-ng keeps the settings file in Roaming folder. (C:\Users\user\AppData\Roaming\XCP-ng) When I deleted it I could re-register the servers.

    @nuentes Oh no, no. Your system is not destroyed beyond repair. It can be repaired. It's just that it is almost impossible or too much of a hustle for anyone to try to help you over forum. Someone has to sit in front of your machine to do it. My only guess is that ChatGPT instructed you to make changes based on a CentOS system but XCP-ng and Xen virtualization in general is much different than regular CentOS. It has two stage boot process. First the Xen kernel boots and then a special virtual machine called Dom0 is booted. What you are accessing and reconfiguring is in fact this VM, not the underlying "system". So it's like a two layer system and some configuration must be done on Xen layer, some on Dom0 layer. I'm unfortunately unfamiliar with exact specifics on kernel and initrd image generation for this case so I can't spot where thing have gone wrong. In short terms. Instead of going back and forth and trying a lot of different things, it's more time saving and simpler to reinstall the system and restore metadata if you already have a backup.

    @Pilow, Well, it was a major pain, but I got both hosts on eth0 for management & eth2 for Storage10g & it's working now. I wish XOA made this an easier process.

    @TestForEcho No ETA for now. Even before supporting QCOW2 on LINSTOR, we have several points to robustify (HA performance, potential race conditions, etc.). Regarding other important points: Supporting volumes larger than 2TB has significant impacts on synchronization, RAM usage, coalesce, etc. We need to find a way to cope with these changes. The coalesce algorithm should be changed to no longer depend on the write speed to the SR in order to prevent potential coalesce interruptions; this is even more crucial for LINSTOR. The coalesce behavior is not exactly the same for QCOW2, and we believe that currently this could negatively impact the API impl in the case of LINSTOR. In short: QCOW2 has led to changes that require a long-term investment in several topics before even considering supporting this format on XOSTOR.

    @Davidj-0 Merci pour le retour, j'utilisais aussi une Debian pour mon test ^^
