From: David Matlack <dmatlack@xxxxxxxxxx> This tracepoint is called by nested SVM during emulated VMRUN. Call also during emulated VMLAUNCH and VMRESUME in nested VMX. Attempt to use analagous VMCS fields to the VMCB fields that are reported in the SVM case: "int_ctl": 32-bit field of the VMCB that the CPU uses to deliver virtual interrupts. The analagous VMCS field is the 16-bit "guest interrupt status". "event_inj": 32-bit field of VMCB that is used to inject events (exceptions and interrupts) into the guest. The analagous VMCS field is the "VM-entry interruption-information field". "npt_enabled": 1 when the VCPU has enabled nested paging. The analagous VMCS field is the enable-EPT execution control. "npt_addr": 64-bit field when the VCPU has enabled nested paging. The analagous VMCS field is the ept_pointer.
