--- Comment #4 from mlevitsk@redhat.com ---
I did some more testing:
1. I double checked that INTEL_ARCH_LLC_MISSES_INDEX is the only event that
fails,
test survived whole night with only it commented out.
2. using CLFLUSH instead of CLFLUSHOPT doesn't help
Should we disable this event for now to avoid the failure until we figure out
how to use this event in a reliable way?
Best regards,
Maxim Levitsky
PS: I also did initial testing for running this test nested - it fails with
invalid guest state in L1, but only sometimes.
I'll investigate that further soon.
