@juergh I think I installed hwe-6.14 - the instructions didn't explicitly say how to install it so I enabled proposed and then ran:
sudo apt install linux-generic-hwe-24.04-edge/noble-proposed After rebooting it shows I'm running the 6.14 kernel $ uname -r 6.14.0-24-generic I installed it on 2025-07-04 and its been running fine since. The GPU passthrough works and I've rebooted 3 times without any issues with the KVM daemon - so maybe this issue is solved (though I haven't updated packages since, and am not sure if the issue was anyway related to updates of the kernel package.) Another issue that maybe improved is GPU resets. With the 6.11 kernel every few days (if not more often) my screen would go blank for several seconds and occasionally the gpu reset would even log me out requiring me to login to the display manager again. Maybe its too early to tell, but I don't think I've experienced this issue since updating to the 6.14 kernel. apt is showing there's updates available for me to install (for linux- image-6.11.0-26-generic.) If I install this will it just update grub and have me boot back into the 6.11 kernel? I'm fine moving back to the standard kernel since I feel I've now successfully tested 6.14. Or do I need to do something else to move back to the 6.11 kernel (e.g. uninstall the 6.14 packages)? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2107285 Title: KVM VM with GPU passthrough won't start To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/2107285/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
