@HolgiB thank you. Since my instances are just for homelab, I'm waiting for a solution from Citrix/XS/Vates. I can afford to be stubborn and expect the parties that failed to supply a solution. But again thank you, if this was production I would do so. Or just use my backups and migrate data to a working instance. I'm just really curious how this happened and want to test if a solution is provided and when.

@stormi disabling that option won't let my VM boot. Just more BOD. I will continue trying things of course. My main concern is access to proper agents as the one referenced in XCP-ng docs seemed to have been developed and also abandoned in the year 2019! The other options have literally failed. This issue would frankly keep me from having confidence in the stack if I was to run in production. How could Citrix or XenServerProject let this happen? Including Vates, we're talking about a pretty mature system/dev stack at this point.

@clip I will add that I'm experiencing same results with Windows 11 (no TPM used) and a Ryzen hypervisor. Both working and blue screening VMs have uefi boot firmware and each have the same 9.3.3 XenServer Tools updated on 6/7/24. No MS update issues pre 6/17/24

@KPS I have the Citrix package installed and the XCP-ng "manage PV drivers via Windows update" toggled on. I remember being very careful on my initial setup and following the proper guidelines, but I wouldn't bet my life on it.

The more concerning thing for me is that I have 1 vm with the same configuration and it's fine, with another 2 blue screening. They are literally clones of each other. Maybe the others will fail soon too (I know it takes a couple reboots).

I have backups and remediation options to attempt as others have posted here. Ie: uninstall Citrix package, update, toggle off auto update etc. I feel confident I'll find the right combo.

Again, just strange that I've had none of these issues after all my years using this hypervisor. ... I love Vates and this community... So I'm not overly concerned yet.

Great work keeping an eye on this and thank you!!!!

@Toni yep. I had to do this too. 2 of my 5 Windows VMs got blue screened by the Citrix drivers. There is something going on beyond a doubt! My VMs have been flawless for years now until yesterday 6/17/24.

@StormMaster thank you. This workaround did exactly what i needed.
