Hello,
The following two patches address an integration issue between KVM and KGDB. The issue described in the patches can be triggered with vanilla kernels that enable KGDB and KVM together on x86 (more specifically, we bump into this with Fedora's 3.11 kernel from FC19).
On a kernel enabled with KGDB, running with kvm-unit-tests should reproduce the issue. On VM hosts servers where an admin accidently left an active KGDB, and unprivilged guest might be able to bring the host down.
Patches apply to linux-next and earlier kernels.
