** Description changed: Dear all, We faced a kernel oops on KVM from a null pointer derefence on one of our hypervisors (running several KVM VMs). This led 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). + We're using Ubuntu 12.04LTS.
