The command line of kvm:

Comment 2 Marc-Andre Lureau 2011-06-16 05:16:32 UTC 
I can't reproduce the crash with spice-server-0.8.1-1.fc15.x86_64 and qemu-kvm from Fedora 15 qemu-common-0.14.0-7.fc15.x86_64.

RedUEC, could you try with more recent versions and provide more informations about the circumstances of the crash?
