I have to correct myself. Indeed there is a big difference. As I 
disabled the gtk2 flag, gtk3 is used now. Before, I sometimes had
some graphic glitches when I moved windows or scrolled window 
content in the guest machine. It seems that these glitches are not
there any longer. And it also seems, that graphics output is s little
bit smoother now. So THX for your post. :-)

I also disabled now gtk2, sdl and sdl2 because I don't really need it. 
I have to leave on gtk, because I run qemu in a gtk window. I don't 
notice any difference.

  Strange.  I kept making changes until it worked.  Now that it works,
I'll stop tweaking it.  Whatever works for you, or me.

I have all gtk and sdl flags enabled and don't have problems with

[gentoo-user] About gentoo linux PCI passthrough

2016-04-02 Thread Nicol TAO 

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA256

Hello, every gentooers!

I am running Gentoo with the latest Virt-Manager/Libvirtd/KVM windows
2003 as Guest OS. Because the Broadcom of under the host environment
works terrible of the performance and stability, so I want to pass it to
my Guest windows 2003 OS.

I followed the [tips](https://wiki.gentoo.org/wiki/QEMU/Options), and
added my PIC wireless NIC through virt-manager, but when I boot,
virt-manager complains as:

bvirtError: unsupported configuration ：host doesn't support passthrough
of host PCI devices

Does anyone has this experience?
Here some of my info:

Or perhaps the maintainer hasn't even considered the idea and all it needs
is a feature request.

  The problem appears to be the "sdl" flag.  It slows down things by
adding one more layer of middleware and overhead.  I also got rid of the
"gtk2" flag, for the same reason.  By building QEMU with "-sdl" and
"-gtk2", I get playback that is indistinguishable from playback on the
host.  Here is the build that works properly "emerge -pv qemu"...

I don't think it's a case of "there needs to be".
I think it's more a case of "you want it to be to solve this special
problem you have", and perhaps the logrotate maintainer doesn't agree.
