I am trying to install Fedora-Live-Workstation-x86_64-21-Alpha-TC4.iso
in qemu.

The qemu command line is:

ionice -c 3 qemu-kvm -enable-kvm -global qxl.ram_size=1x1024 -m 2048M -smp 4 -drive file=./Fedora-Live-Workstation-x86_64-21-Alpha-TC4.iso.qcow2,index=0,media=disk,cache=unsafe -localtime -serial file:/tmp/qemu-Fedora-Live-Workstation-x86_64-21-Alpha-TC4.iso.qcow2-output.log -name Fedora-Live-Workstation-x86_64-21-Alpha-TC4.iso.qcow2 -cdrom /local/mfabian/iso/f21-Alpha-TC4/Fedora-Live-Workstation-x86_64-21-Alpha-TC4.iso -boot c -spice port=6000,disable-ticketing,streaming-video=off -vga qxl -display vnc=:4 -net nic -net user,hostname=Fedora-Live-Workstation-x86_64-21-Alpha-TC4.iso.qcow2,hostfwd=tcp::5555-:22 -monitor stdio -usb

In the first screen, I click on "Install".

Then I select Japanese language and and an US English keyboard layout and proceed with the installation.

The screen flickers extremely. It is very hard to enter the passwords
for root and the user while the installation proceeds. 

The screen flickers all the time between some blue desktop background
picture and anaconda proceeding with the installation.

See the attached video how this looks like.

It happens no matter whether using a vnc client or a spice client.

I found this while doing installation in kvm.

I didn't see this on Gnome Boxes but am seeing it on VirtualBox
