http://bugzilla.opensuse.org/show_bug.cgi?id=1202054 Bug ID: 1202054 Summary: starting KVM guest crashes kernel 5.14.21-150400.24.11-default Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.4 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: seife@novell.slipkontur.de QA Contact: qa-bugs@suse.de Found By: Community User Blocker: --- Starting a KVM guest crashes the host OS. This is the relevant part of dmesg.txt I also have a kdump vmcore if that helps. It works fine with the non-updated 5.14.21-150400.22-default kernel.
