When passing through a TPM device to a qemu Windows 10 guest Windows will fail to initialize the TMP driver with the reason: 'device cannot find enough free resources'. The bug was investigated and a patch provided upstream for qemu relesae 2.6 onwards. See original bugzilla thread here https://bugzilla.redhat.com/show_bug.cgi?id=1281413.
I've confirmed this bug also affects the stock qemu package (1:2.5+dfsg-5ubuntu10.4) in 16.04. To resolve I built the qemu 2.6.1 tarball and tested which solved the problem.
My understanding is that qemu 2.6 is slated for 16.10 only, can this updated code be brought into the 16.03 LTS family also?
