If it is of all useful the patched code in qemu 2.6.1 and 2.7.0-rc4 actually doesn't allow me to use Bitlocker with my TPM (my end game), basically the windows guest shows the passed through TPM as functional however windows tpm admin says it can't find a compatible tpm device. I'm uncertain if its a user config issue (don't really see how) or another related/unrelated bug. Regardless I filed this (https://bugs.launchpad.net/qemu/+bug/1615823) bug report against qemu and am pending a response on that.
Thank you for the confirmations Nish.
