[Mageia-dev] Please remove qemu, and qemu-img from Mageia 3.
During testing of updates to qemu, and x11-driver-video-qxl, it has become very clear that no-one could possibly be using these packages, as they are so slow, as to be useless. Over 6 hours to do a net install of a kde x86-64 system, on hardware where that would normally be under 20 minutes. There are many problems with xorg crashing, mouse pointer not being where the pointer is shown, etc. These bugs are described in https://bugs.mageia.org/show_bug.cgi?id=8938 Please drop these useless packages, so we don't have to test or install security updates for them. Thanks, Dave Hodgins

While I don't know for x11-driver-video-qxl, qemu is useful for things different from installing recent linux distros : as example, old OS like DOS/Win 3.11 run better in it than in Virtual box. So please don't remove it.
