Something like the one below (with the error at the end)?
What do you mean "events at $RIP" ? I see 2 patterns here
with references to $RIP. Many like this:
kvm-0.12.5-1301 [001] 47965.427622: kvm_page_fault: address fee00080 error_code 6
kvm-0.12.5-1301 [001] 47965.427622: kvm_emulate_insn: 0:d0202002: 89 1d 80 00 99 d0 (prot32)

which are repeated without changes over and over again.
And at the end, several like this:

(with different kvm_emulate_insn each time), which finally ends with
kvm-0.12.5-1301 [001] 47965.428804: kvm_emulate_insn: 0:d0202041: cf (prot32)
kvm-0.12.5-1301 [001] 47965.428805: kvm_emulate_insn: 0:d0202041: cf (prot32) failed
Note it's the same openbsd which triggers insane amount of
host_state_reloads, so the trace is quite, well, large :)
Thanks!
