# Test AMD Nested Event Injection.
#
# 1. Setup nested environment (L1) and Create VM (L2).
# 2. Inject an NMI (Vector 2, Type 2, Valid) into L2 via VMCB EVENTINJ.
# 3. Launch L2.
#    - This forces KVM L0 to parse EVENTINJ and handle the injection.
#    - We expect L0 to succeed without crashing.
#
# Arguments for INJECT_EVENT:
# vm_id=0
# vector=2 (NMI)
# type=2 (NMI)
# error_code=0
# flags=1 (Valid=1, EV=0)
