Hello, when i first install my setup i used alex's blog : http://vfio.blogspot.fr/2015/05/vfio-gpu-how-to-series-part-3-host.html
Thus it seems i installed qemu by adding fedora virt preview repository and updating fedora :
https://fedoraproject.org/wiki/Virtualization_Preview_Repository

Problem is when i list my packages with dnf list qemu i got :
qemu.x86_64      2:2.5.-6.fc23      fedora-virt-preview

Problem is i cannot remove this package using this name, it doesn't work.
Using dnf update i can see on the updated list :

qemu-common
qemu-guest-agent
qemu-img
qemu-kvm
qemu-system-x86

So question, how to get rid of this or just updating qemu to 2.5
If i remove the repo and upgrade the system to fedora 24 will this remove the package thus allowing me to get the new version of qemu?
