--- Comment #2 from Sean Christopherson (seanjc@xxxxxxxxxx) ---
This is going to sound completely ridiculous, but can you try the fix for the
guest RFLAGS corruption issue in the return thunk?  It's definitely unlikely
that the _only_ symptom is an unexpected OOM, but it's theoretically possible,
e.g. if your setup only triggers KVM (bare metal host) emulation in a handful
of flows, and one of those flows just happens to send a single Jcc in the wrong
direction.
