[PATCH 0/4] KVM: nSVM: first step towards fixing event injection

[Paolo Bonzini]

Event injection in nSVM does not use check_nested_events, which means it
is basically broken.  As a first step, this fixes interrupt injection
which is probably the most complicated case due to the interactions
with V_INTR_MASKING and the host EFLAGS.IF.

This series fixes Cathy's test case that I have sent earlier.

Paolo Bonzini (4):
  KVM: nSVM: do not change host intercepts while nested VM is running
  KVM: nSVM: ignore L1 interrupt window while running L2 with
    V_INTR_MASKING=1
  KVM: nSVM: implement check_nested_events for interrupts
  KVM: nSVM: avoid loss of pending IRQ/NMI before entering L2
