aaaand vmport=off is not supported in rhel7, it seems
"qemu-kvm: -machine pc-i440fx-rhel7.0.0,accel=kvm,usb=off,vmport=off:
Invalid parameter 'vmport'"

So, I manage to make it work. I needed to disable the tablet input
device. It is working even without vmport=off.

With tablet device, the videos I've made are what happened with me.
