[Bug 937652] New: nbd shutdown crash
http://bugzilla.suse.com/show_bug.cgi?id=937652 Bug ID: 937652 Summary: nbd shutdown crash Classification: openSUSE Product: openSUSE Distribution Version: 13.2 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: cbosdonnat@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Created attachment 640583 --> http://bugzilla.suse.com/attachment.cgi?id=640583&action=edit test script triggering the problem When shutting down a libvirt-lxc container with an NBD mounts, we sometimes get a crash. Steps to reproduce: * Get libvirt, and virt-sandbox from the Virtualization project * Install guestfs-tools * systemctl start libvirtd * Run the attached test script. The QEMU tests can be commented in it as those aren't the ones triggering the bug. Note that the crash may not happen at each run of the script, don't hesitate to run it several times if needed. What happens: * the 'sandbox' container isn't correctly terminated due to the qemu-nbd segfaulting. -- You are receiving this mail because: You are on the CC list for the bug.
