Do you get any output on the console where you ran the kvm command?
If you run kvm with "-vnc :1" and then run "gvncviewer localhost:1", does that work better?
Assuming it still breaks under vnc, then, again using gvncviewer, at the top left you can choose "send key -> ctrl-alt-f2". Please do that, then look at the end of /var/log/syslog. Is anything interesting there?
Which window manager are you using on the host? (I vaguely recall the SDL library in the past has had some trouble in certain window managers)
