Description Ales Kozumplik 2013-09-13 14:29:49 UTC 
Description of problem:
In a KVM machine, xorg takes 40%-50% CPU the whole time the Yum payload is installing the packages. This renders the machine very slow (e.g. to fill in the root password)

Additional info:
This could be because of busy waiting somewhere or a misuse of X by one of the Anaconda components.
Comment 1 Ales Kozumplik 2013-09-13 14:30:50 UTC 
(reproduced on the f20 devel compose circa 0908)
Comment 2 Vratislav Podzimek 2013-09-23 15:18:58 UTC 
Could you still reproduce this with some F20 Alpha image? It works for me, Xorg takes something between 1 and 10 % of CPU, usually 1 %. Unless we have a reproducer with a recent image I'm gonna close this bug as WORKSFORME.
Comment 3 Ales Kozumplik 2013-09-27 08:59:35 UTC 
Please point me to a working F20 image. Just tried with:

http://download.eng.brq.redhat.com/pub/fedora/linux/development-snapshot-20130926/20/

And anaconda hangs taking 100% of the CPU.
Comment 5 Ales Kozumplik 2013-09-27 13:52:42 UTC 
I see Xorg at around 10-15% during the installation which I guess is fine (by today's Fedora standards). Please go ahead closing it.
