Windows 2025 Standard 24H2.11 (iso release of sept 25) crash on reboot with "INACCESSIBLE BOOT DEVICE 0x7B" in XCP 8.2.1 and XCP 8.3
-
I've narrowed down the problem to a set of patches. Will continue to diagnose.
-
Just tested Win 11 25H2 iso just released today. No issues with fresh install.
Management tools installed and Citrix PV drivers installed via windows update.
-
@acebmxer did you test latest Xen Tools ?

7 days old though -
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.
-
The cause has been found, and a fix is under way. Stay tuned.
-
@dinhngtu Thats great news!
-
Hi all, here's a pre-build of the fix for anyone who wants to test (8.3 only):
wget https://koji.xcp-ng.org/repos/user/8/8.3/xcpng-users.repo -O /etc/yum.repos.d/xcpng-users.repo yum update --enablerepo=v8.3-u-ndinh1 -
@dinhngtu will be released also for 8.2.1?
-
-
@dinhngtu On a quick test, the ISO boots and installs. When the VM boots from the HD it crashes (and on reboots).
Updating XCP 8.3 with
qemu-4.2.1-5.2.12.2~fixvwc1.1.xcpng8.3.x86_64solves the issue and the installed windows image boots correctly without any additional changes. -
That's great! \o/
-
@olivierlambert this problem can cause a crash on update of windows 2025 VM on xcp-ng 8.2.1 or remains only a problem for fresh install?
-
8.2 is EOL, and also IDK how it's affected by this issue.
-
@francesco-maria I haven't determined what exact conditions would trigger the issue. It seems to only happen on new installations for now, but it could very well change in the future. Though as long as you keep the Xen drivers installed, things should be OK.
-
@dinhngtu Thanks for info. I config that manual apply of fix solve the problem on my 8.3.
I only chance the yum update in yum update --enablerepo=xcp-ng-ndinh1
