Can you retry w/o compression?

This works for me (tm). Attached my configuration. I tried with f13 linux console and rhel55 X install, both worked with keyboard and mouse.

Which (qemu-kvm & kernel) version did you use? Should I retry it in qemu-kvm-0.12.1.2-2.48.el6.x86_64 ? or the latest version ?
This ones work for me. [root@deus ~]# rpm -qa kernel qemu-kvm kernel-2.6.32-37.el6.x86_64 qemu-kvm-0.12.1.2-2.78.el6.x86_64

I try again with #commnet5 steps, cannot reproduce this bug in qemu-kvm-0.12.1.2-2.82.el6.x86_64 kernel 2.6.32-38.el6.x86_64
