Public bug reported: Dear all,
We faced a kernel oops on KVM from a null pointer derefence on one of our hypervisors (running several KVM VMs). This lead us to a serie of kernel oops affecting all the VMs and finally, the host crash. We couldn't really establish where from the first oops was comming (in order to reproduce the crash). You'll find attach the extract of syslog where you have the really first oops, and all the followings. We're using Ubuntu 12.04LTS. We're using latest releases available on it, including for KVM. We're using kernel 3.8 due to hardware constraints. And we're using kernel 3.8.0-33-generic due to regressions in newer kernels (not yet reported). ** Affects: kvm (Ubuntu) Importance: Undecided Status: New ** Attachment added: "Kernel oops" https://bugs.launchpad.net/bugs/1352794/+attachment/4170197/+files/syslog -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to kvm in Ubuntu. https://bugs.launchpad.net/bugs/1352794 Title: Null pointer dereference in mmu_set_spte.isra To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kvm/+bug/1352794/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
