Hello fellow qubes users, I have tried for quite some time but i am not able to have a stable windows-vm. I successfully can run windows10 and windows11 but after a while (it can be 2min or 45min) i run into a blue screen KMODE EXCEPTION NOT HANDLED in windows10 (+ continous beeping when browser i…

That’s great to hear! Can you attach block devices, not as USB devices?

Is block device attachment with Xen PV Disk Drivers the only thing that is not working for you in QWT? Or nothing from QWT works at all (clipboard/file move/copy/etc)? There seems to be an issue with Xen PV Disk Drivers and btrfs: Disable direct IO on Btrfs based s…

@sweet.cheddar Thank you for sharing what you have tried. I have exactly the same problem. BSOD with windows 11 hvm. On the same system, the NV41. Fresh installed hvm without QWT. Could you finally get it working ?

Did you try this? [image] Windows Bluescreen ( KMODE EXCEPTION NOT HANDLED ) General No, add this line at the end of /etc/default/grub instead: GRUB_CMDLINE_LINUX="$GRUB_CMDLINE_LINUX split_lock_detect=off" Run this command to update the grub config: sudo grub2-mkconfi…

No, thank you for the hint. I will try tomorrow and report back ! Sorry, I did forget. I have already added the mentioned line there and reloaded. Did not help unfortunally.

Hello, I haven’t manage to get it working. I contacted nitropad a year ago, see: [image] Windows VM BSOD (KMODE EXCEPTION NOT HANDLED) (IRQL NOT LESS OR EQUAL) General So i tried asking to xen team but it didn’t solve my issue. I also asked to the vendor of my laptop, N…
