Michael,
Yes.. SIER has different value in baremetal and virtual machine
due to different MSR[HV] value. I will correct it. Originally I only
tested in virtual BE/LE machines.
Currently all tests cases (with fix) passed on one baremetal P8 machine
with LE OS installed. And I will try to find another baremetal with BE
OS installed to test.
Thanks for indicating it.
BR,
Simon
