You might want to investigate the new upstream Android emulator
work (the key term is "ranchu") which should combine Google's
GL acceleration support with a new enough QEMU to support KVM
on ARM. This is all still rather work-in-progress though so
you'd need to be prepared to get your hands dirty debugging
and fixing stuff. In the longer term it's probably the best
solution to what you're aiming for I suspect.

I just found out that mouse and keyboard are working correctly BUT the issue is 
that QEMU graphical window is badly refreshed... It's also linked to my other 
message about the graphical issue.

- I start my guest through QEMU and I get a black screen on QEMU graphical 
window

GRAPHICAL part
- I switch to QEMU monitor and perform "sendkey ctrl-alt-f1" to switch to TTY1 
guest console
-> I switch back to guest interface (previously full black) and TTY1 prompt is 
visible
- I switch to QEMU monitor and perform "sendkey ctrl-alt-f7" to switch to guest 
desktop
-> I switch back to guest interface and desktop is now visible...
-> So I guess desktop was already "there" but window was not "refreshed"

KEYBOARD/MOUSE part
- I switch to QEMU monitor and perform "sendkey ctrl-alt-f1" to switch to TTY1 
guest console
-> I switch back to guest interfaceand TTY1 prompt is visible
- I press several keys like "abcdefg"
-> Nothing is visible next to the prompt
- I switch to QEMU monitor and perform "sendkey ctrl-alt-f7" to switch to guest 
desktop
- I switch to QEMU monitor and perform "sendkey ctrl-alt-f1" to switch to TTY1 
guest console
-> Text "abcdefg" is now visible
-> It seems again that switch between TTY1 and desktop refreshes keyboard and 
mouse events (also tested the same way with mouse). Switch between TTY1 and 
QEMU monitor does not have any effect.

Does it helps you on you issue ?
