I ran the tests mentioned in launchpad comment #40 on a DD2.3 witherspoon 
machine with GA firmware. Aside from the issue caused by the missing kernel 
patch, QEMU behaved as expected.

One thing of note is that the following firmware features are disabled:

ibm,opal/fw-features/fw-bcctrl-serialized
ibm,opal/fw-features/fw-count-cache-disabled

which means that 'cap-ibs=fixed-ibs' and 'cap-ibs=fixed-ccd' are always
refused by KVM in this machine.

I attached the test results as qemu-dd2.3-sanity.txt
