Gentoo does not use the VGA bios that is bundled with QEMU. Instead, it substitutes QEMU's VGA bios with a file from sys-firmware/vgabios, which is inferior. Due to a known bug (see Debian bug report), with Gentoo's vgabios, Windows 8, when running in qemu-system-x86_64 -vga std, lists only 1024x768 as the available resolution, and grays out the resolution selector. With the vgabios that ships with QEMU, or with the vgabios that can be built from seabios sources, switching the resolution works. I have not tested the patch mentioned in the Debian bug report. Reproducible: Always Steps to Reproduce: 1. Install Windows 8.1 in KVM-enabled QEMU with -vga std. 2. Right click on the Windows desktop. 3. Select the "Screen resolution" menu entry. 4. Look at the available resolutions. Actual Results: Only 1024x768 is shown, and the selector is grayed out. Expected Results: A lot of resolutions should be shown, including 1920x1200. You can verify the fix by replacing /usr/share/qemu/vgabios-stdvga.bin This might be considered a duplicate of bug #523134. $ emerge --info Portage 2.2.14 (python 2.7.8-final-0,

Please post your `emerge -vpq sys-firmware/vgabios' output in a comment.
[ebuild R ] sys-firmware/vgabios-0.7a-r1 USE="-binary -debug"
most likely this won't be fixed. instead we'll go with bug 523134 and use that as the default vgabios provider.
Bug 523134 says: "updating qemu itself to use the new seavgabios files will be tracked by bug 529862", i.e. here. And nothing is done on this front. PING.
QEMU still does not use seavgabios. PING.
if you want to help, post a patch. otherwise, stop spamming. you're really just annoying people here.

Oops, forgot to require the seavgabios use flag on seabios...
(In reply to Alexander E. Patrakov from comment #8) yep, you'll need to update seabios dep also we'll want to wait for the next release to make this change as the save/restore logic is messy when bios chunks change :/
qemu-2.5.0 ebuild is in the tree, without this fix. So you still have the same excuse "we'll want to wait for the next release" because of the save/restore logic.
qemu-2.8.0 is in tree, but we're still using outdated VGA bios... I'm even using "-L /usr/share/seavgabios" QEMU option to somehow workaround this problem
All, I have pushed app-emulation/qemu-2.9.0-r50 to the tree that contains the firmware change. (It is currently not keyworded to minimize surprises.) Please test! commit 189f585f9d2ea7091771fb6aee6d7d975b482e4e Author: Matthias Maier <tamiko@gentoo.org> Date: Tue May 2 19:29:55 2017 -0500 app-emulation/qemu: replace vgabios firmware with seavgabios, bug #529862 Special thanks to Alexander Patrakov for the ebuild patch. - Dropping keywords due to potential issue with migration and resume of hibernated guests. See, e.g. bug #560050 Package-Manager: Portage-2.3.5, Repoman-2.3.2
