I tested with:
edk2.git-ovmf-x64-0-20151117.b1317.g386cdfb.noarch.rpm
$ git show 386cdfb

which I used for a little while now and to see if its just my "old" OVMF
I also tested the newest version from your jenkins repo (much thanks for
them!!):
git show 05b2f9c

So without csm.
The OS is 64bit windows 7 professional SP1
The QEMU command for my test:
./x86_64-softmmu/qemu-system-x86_64 -boot d -cdrom W7SP1_PROFESSIONAL.iso -m
1024 -smp 2 -enable-kvm -cpu host -drive
if=pflash,format=raw,unit=0,readonly,file=OVMF_CODE-pure-efi.fd -drive
if=pflash,format=raw,unit=1,file=/tmp/OVMF_VARS.fd
Happy to provide more details/test if needed.
best regards,
Thomas
