Last modified: 2014-03-16 23:30:21 EDT
Description of problem:
Because cirrus causes kittens to kill kittens in a horrible kitten-killing arena.
(Others can elucidate on cirrus' lameness if so desired.)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Look at qemu defaults
2. See 'cirrus'

I don't think we can do this because some OS (eg Fedora 16) have QXL drivers which are pretty fubar and thus should not be used.
We could at least switch to the STDVGA driver though, which should be an improvement.
Any use of QXL should be controlled by libosinfo (or equivalent per-OS config databases in virt-install, etc)
OSes can fall back to vesa (and ours should be fixed).
We can't retroactively fix existing released media. This kind of issue is exactly why we maintain databases of per-OS default hardware drivers.
Yeah, closing this WONTFIX. Changing the default at the qemu level just isn't an option unless the change was upstream first (and it's highly unlikely upstream would make this change).
As danpb mentions, the way forward with this is getting VM building tools to use libosinfo.
