Copy Fail is documented in VSA-2026-013, we don't have one for Dirty Frag yet as we're still investigating XCP-ng side regarding it. For XOA, unattended updates should have installed the patched debian kernel, you just need to reboot it. Debian security tracker states they are both fixed: https://security-tracker.debian.org/tracker/CVE-2026-31431 https://security-tracker.debian.org/tracker/CVE-2026-43284

@olivierlambert do you know who on XOA side can have a look?

This works fine, indeed. Thanks!

The issue is there's a VDI that's not in the right map. It's hard to tell why without having a deeper look.

Thanks, this works!

Since it was somewhat critical (urgent migration from other pool), I had to switch the pool masters and had to restart the xcp028. But I downloaded the system log. Maybe you find the cause of the problem there? BTW, before restarting the host, I was not able to download these logs (failed).
