What's the status with upstream?
Comment 5 Gerd Hoffmann 2013-10-17 09:03:58 UTC 
What is the RHEL-6 status (i.e. is it a regression)?
Which driver is used by windows (check device manager)?  cirrus or generic?
Did you test qxl with or without guest drivers?

1. RHEL6 has no such issue. (test on RHEL7 with qemu-kvm-1.4.0-3.el7.x86_64 hit this issue as well, so it is not a regression.)
2. Guest use cirrus driver. (has a screenshot in attachment)
3. Guest GUI work properly both with and without qxl driver.
Comment 7 Gerd Hoffmann 2014-01-15 14:28:59 UTC 
Turned out to be a vgabios issue.  With latest seavgabios everything works fine.
So we have to backport some cirrus fixes to seabios ...
Comment 8 Gerd Hoffmann 2014-01-16 15:27:05 UTC 
please retest with seabios-1.7.2.2-8.el7
[ likely a dup of bug 979898 ]

Tested this issue with seabios-1.7.2.2-8.el7, failed to reproduce.

Command line:
# /usr/libexec/qemu-kvm -net none -M pc -m 2G -cpu SandyBridge -smp 4,cores=2,threads=2,sockets=1 -monitor stdio -vnc :1 -drive file=/home/win2003-32-virtio.qcow2,if=none,id=guest-img -device ide-hd,drive=guest-img,id=os-disk -vga cirrus

Result:
Guest display normally(see attachment in this comment).

As the result above, I'd close this as dup of bug 979898.
