it seems that qxl is not working correctly with any of the 0.15 releases thus
far. this includes qemu and qemu-kvm.
when I start qemu like so:
qemu-system-x86_64 -cpu host -enable-kvm -m 768 -usb -vga qxl -monitor stdio
I get a black screen.
when I start with -vga std:
qemu-system-x86_64 -cpu host -enable-kvm -m 768 -usb -vga std -monitor stdio
I see the seabios screen, etc.
qemu has been configured like
./configure --target-list=x86_64-softmmu --disable-curses --disable-curl --
audio-drv-list=alsa --audio-card-list=sb16,ac97,hda --disable-bluez --enable-
vhost-net --enable-spice
I've also configured with --disable-vnc and --disable-opengl with the same
results
Am I using this wrong, or is this a bug?

I recently had black screen problems with QXL in 0.14.x that turned out to
actually be a Seabios bug due to the default 64MB vram QXL has. I suspect
this would hit 0.15.x builds too. If this is what you're hitting, then
reducing the vram to 32MB is a temporary workaround that should help, eg
-vga qxl -global qxl-vga.vram_size=33554432

That took care of the black screen. Thanks.

It is a seabios issue indeed.

There is a fixed seabios binary @ http://spice-space.org/download/seabios/
Patches are all upstream, so just fetching the latest seabios bits (git
master branch) and building yourself will work too.
cheers,
Gerd

Yep, I put that bios in and removed -global qxl-vga.vram_size=33554432 from
the comand line, and it worked just fine.
Thanks.

Great, is there an intention to rebase Seabios in QEMU to pull this in
before the release of 0.15 ?

Anthony doesn't want change the bios that shortly before cutting a
release. So my backup plan is to get that into master, then 0.15.1

Ok, I guess Fedora users can get the fix anyway, since we build seabios
from standalone source that we can trivially patch.
