"hw.vmm.trace_guest_exceptions". To enable this feature set the tunable to "1" before loading vmm.ko. Tracing the guest exceptions can be useful when debugging guest triple faults. Note that there is a performance impact when exception tracing is enabled since every exception will now trigger a VM-exit. Also, handle machine check exceptions that happen during guest execution by vectoring to the host's machine check handler via "int $18". Discussed with: grehan MFC after: 2 weeks |
