https://bugzilla.kernel.org/show_bug.cgi?id=67761 Bug ID: 67761 Summary: Kernel fails to boot under virtualization, kernel panic in intel_pstate_timer_func Product: Virtualization Version: unspecified Kernel Version: 3.13.0-0.rc4.git5.1.fc21.x86_64 Hardware: All OS: Linux Tree: Fedora Status: NEW Severity: normal Priority: P1 Component: kvm Assignee: virtualization_kvm@xxxxxxxxxxxxxxxxxxxx Reporter: kashyap.cv@xxxxxxxxx Regression: No Description of problem ----------------------- Libguestfs fails to create an appliance with (either through 'direct' of 'libvirt' backends with a Kernel panic. libguestfs-test-tool result below. [I encountered this when I was running libguestfs-test-tool -- http://libguestfs.org/libguestfs-test-tool.1.html, which boots into a Kernel under QEMU] Version ------- $ uname -r; rpm -q libvirt libguestfs qemu-system-x86 3.13.0-0.rc4.git5.1.fc21.x86_64 libvirt-1.1.3.1-2.fc20.x86_64 libguestfs-1.25.18-1.fc21.x86_64 qemu-system-x86-1.6.1-2.fc20.x86_64 How reproducible: Consistently. Steps to Reproduce ------------------ Run libguestfs diagnostics test tool: $ export LIBGUESTFS_BACKEND=libvirt $ guestfish get-backend libvirt # Run the tool: $ libguestfs-test-tool Repeat the above with 'direct' backend: $ export LIBGUESTFS_BACKEND=direct $ guestfish get-backend direct $ libguestfs-test-tool (NOTE: SELinux was Permissive in both cases) Actual results -------------- Libguestfs
