Hi,

I recently updated qemu to 1.6.0 and found OVMF just showed a blank
screen when kvm was enabled. I tried to dump OVMF log with the
following commond but nothing was stored in debug.log.

qemu-system-x86_64 -s -enable-kvm -bios OVMF.fd -debugcon file:debug.log 
-global isa-debugcon.iobase=0x402

The kvm trace was recorded with "trace-cmd record -b 20000 -e kvm"
and uploaded to the following link:
https://docs.google.com/file/d/0B9hbtlc_aK_gcGh2TDZLUVlzWWc/edit?usp=sharing

I found a similar case with kernel < 3.9, but I already upgraded linux
kernel to 3.10.5, so this may be another bug.

Cheers,

Gary Lin
